The invitation found Alex in a flat belonging to a man who had been dead for eight months.

Alex hadn’t killed him. He hadn’t even known him, which made the arrangement one of the more uncomplicated parts of his current life.

The flat was on the third floor of a narrow building in Bermondsey, above a laundrette that stayed open until midnight and beside a takeaway where the owner had stopped asking questions after Alex fixed the ancient till. Its legal tenant had died in Spain, the landlord continued collecting rent through an automatic transfer, and none of the neighbors had known the quiet man in number twelve well enough to realize that the teenager coming and going from his flat wasn’t him.

Alex had been there for nine days.

He’d used two different entrances, never returned by the same route twice, and kept the curtains arranged so he could see the street without anyone seeing him. The electricity was still connected. The boiler produced hot water after he threatened it with a screwdriver, and the cupboards contained several tins that hadn’t expired.

It wasn’t home, but Alex had stopped expecting anywhere to qualify.

He returned shortly after six in the evening, checked the thread across the door, and knew someone had entered before he touched the lock.

The thread remained intact. The small square of transparent tape near the bottom hinge had been lifted and replaced, leaving one corner misaligned by less than a millimeter.

Whoever had entered knew enough to look for traps, but not enough to put them back correctly.

Alex stepped away from the door.

He continued down the corridor without changing pace, passed the stairwell, and pushed through the fire door at the far end. The metal staircase descended toward the alley. He went up instead, climbing to the roof before crossing two connected buildings and dropping onto a balcony one floor below.

The window latch had never worked properly.

Alex slid a thin strip of metal between the frame and the catch. He raised the window without sound and entered the bedroom.

The flat was dark. Streetlight filtered through the curtain, falling across the bed and the cheap wardrobe beside it.

Nothing moved.

Alex stayed crouched beneath the window and listened.

The refrigerator hummed in the next room. Water traveled through the pipes behind the wall. A car passed outside, tires hissing over wet pavement.

Someone breathed near the bedroom door.

Alex took the small aerosol can from his pocket and rolled it across the floor toward the sound.

A hand shot out and caught it before it reached the doorway.

The intruder had good reflexes.

He also looked down.

Alex vaulted the corner of the bed and struck him across the throat with the edge of his hand. The man staggered backward. He was dressed in black from his boots to the close-fitting fabric covering the lower half of his face, which would have seemed ridiculous if he hadn’t been holding a curved knife.

The blade moved toward Alex’s stomach.

Alex caught the man’s wrist with both hands, turned beneath the arm, and drove his shoulder into the man’s chest. The intruder hit the wall. Alex slammed the wrist against the doorframe until the knife fell, then kicked it beneath the bed.

The man recovered quickly. His free hand closed around Alex’s jacket and threw him across the room.

Alex struck the wardrobe hard enough to shake it. The impact jarred the old gunshot wound in his chest. He ignored the flare of pain, ducked the next punch, and drove his heel into the man’s knee.

Something cracked.

The intruder went down with a muffled grunt.

Alex caught him by the collar and struck his head against the floor once.

The man stopped fighting.

Alex stepped back, breathing harder than he wanted to, but nothing felt newly damaged.

He searched the intruder.

There was no identification. The man carried two additional knives, a coil of thin cord, lock picks, and a small glass vial filled with dark liquid.

Alex removed the man’s mask, but he didn’t recognize him.

The sitting room light switched on.

Alex turned, one stolen knife already in his hand.

A second intruder stood beside the sofa.

She was tall, blond, and dressed in dark trousers, a black jacket, and boots that looked military rather than theatrical. She held a gun in a two-handed grip and had positioned herself so the doorframe protected most of her body.

Her aim was fixed on Alex.

Alex kept the knife low beside his leg.

“You’re Alexander Rider,” she said.

“You’re trespassing.”

Her eyes moved to the unconscious man. “Is he alive?”

“I didn’t ask.”

“Put the knife down.”

“You first.”

A man leaned around the doorframe behind her.

He had dark, untidy hair, a long coat, and a leather satchel slung across his chest. His tie had been knotted in a hurry, and his expression suggested he was more interested in the flat than the possibility of being stabbed.

“Technically,” he said, “Colonel Baird isn’t trespassing.”

Alex glanced toward the front door. “She entered without permission.”

“The door was already open.”

“That doesn’t make it an invitation.”

The man considered that. “That’s fair.”

The woman didn’t lower the gun. “Flynn.”

“Right.” He focused on Alex. “We’re here to save your life.”

“That’s usually when people start lying.”

The man on the floor groaned and began pushing himself upright.

Colonel Baird crossed the room in two steps, caught him by the shoulder, and struck him behind the ear. He went limp again.

Alex watched her technique.

She noticed.

“My name is Eve Baird,” she said. “NATO Counter-Terrorism.”

“Congratulations.”

“This is Flynn Carsen.”

“A Librarian,” Flynn added.

Alex looked at the shelves beside the sofa. The dead tenant had owned fourteen crime novels, a collection of gardening books, and an atlas published before the dissolution of the Soviet Union.

“You’re a long way from work.”

“Not that kind of librarian.”

“There’s another kind?”

Flynn entered the bedroom and crouched beside the man on the floor. He pushed the torn sleeve farther up the man’s arm, revealing a tattoo along the inside of his wrist: a green serpent wound around a sword.

“The Serpent Brotherhood,” he said. “Older than the Assassins, more persistent than the Thule Society, and much less interested in subtlety than their name would suggest.”

Alex glanced at Baird. “NATO has a department for this?”

“No.”

“Then why are you here?”

“He can explain that.”

Flynn stood. “The Library selected Colonel Baird as my Guardian. Partner, bodyguard, and current source of most objections.”

“Temporary Guardian,” Baird said.

“The Serpent Brotherhood has spent centuries trying to return magic to the world.”

Alex waited.

Flynn waited too.

“That’s your explanation?” Alex asked.

“It covers the important part.”

“It doesn’t cover any part.”

Baird lowered the gun, although she didn’t holster it. Alex slid the stolen knife inside his boot without taking his eyes off her.

“Someone is killing people whose names appeared on a recruitment list. Yours is on it.”

“What recruitment list?”

“The Library’s.”

Alex’s gaze moved toward the sitting room.

A cream envelope lay in the center of the table. It hadn’t been there when he left.

His full name had been written across the front.

Flynn followed his attention. “You haven’t opened it.”

“I didn’t receive it.”

“It’s addressed to you.”

“That isn’t the same thing.”

Flynn picked up the envelope and examined the seal. “The paper’s new.”

“Does paper usually have an age requirement?”

“The Library hasn’t used this stationery since 1894.”

“Flynn,” Baird said.

He held the envelope toward Alex. “The Library invited you to interview for the position of Librarian.”

Alex didn’t take it. “No.”

“You haven’t heard what the position involves.”

“I don’t care.”

“You’d protect the world from dangerous magical artifacts, lost civilizations, ancient conspiracies, and the occasional alternate dimension.”

“I already said no.”

“The Library doesn’t generally invite people by accident.”

“Then it can consider this a learning experience.”

The envelope slipped from Flynn’s hand.

It didn’t fall.

The cream paper hung in the air between them for several seconds, then turned until Alex’s name faced him.

Alex stared at it.

Flynn brightened. “See?”

“A piece of paper floating isn’t proof of magic.”

“What would it prove?”

“A wire.”

“There isn’t one.”

“A magnet.”

“Paper isn’t magnetic.”

“A controlled air current.”

“The windows are closed.”

Baird swept one hand above and below the envelope before pressing it downward with one finger. It dipped beneath the pressure, then rose when she removed her hand.

“No wire I can feel and no airflow.”

“That doesn’t prove there isn’t one.”

“You’re determined not to believe this.”

“I’m determined not to believe strangers who break into my flat.”

A sound came from the corridor outside the flat. Alex heard soft footfalls, a scrape against the wall, and the faint metallic click of a weapon being readied.

Baird heard it a second later. She raised her gun.

Flynn picked up the invitation.

“How many exits?” Baird asked.

“Three.”

“I counted two.”

“You didn’t count the floor.”

A suppressed shot struck the front door.

The wood splintered inward.

Alex crossed the bedroom, kicked the loose board beside the wardrobe, and pulled the section of flooring up by its edge. A narrow maintenance space ran beneath the wall into the vacant flat next door.

Baird stared at it. “You made that?”

“It was already there.”

Another bullet struck the door.

Flynn knelt beside the opening. “Where does it lead?”

“Somewhere people aren’t shooting.”

“That’s my favorite kind of place.”

Alex dropped into the gap first. Baird caught Flynn by the coat and pushed him after Alex, then followed. The space was narrow, filled with dust, wires, and pipes that gave off enough heat to make breathing uncomfortable.

Someone forced the front door open behind them.

Alex crawled faster.

The wall ahead had been weakened around an old plumbing access panel. He struck it once with his shoulder. Plaster broke outward into the empty flat.

He rolled through and came up beside a sheet-covered table.

Baird emerged behind Flynn. She pulled the panel back into place as footsteps entered Alex’s flat.

“We need to reach the street,” she whispered.

“They’ll have the stairs covered.”

“Roof?”

“Covered if they’re competent.”

Flynn looked around the empty room. “We don’t need the stairs.”

He walked toward a narrow cupboard near the kitchen and drew a heavy brass key from his satchel.

Alex caught his sleeve. “That’s storage.”

“Doors are rarely only one thing.”

Flynn fitted the key into the cupboard lock and turned it. He opened the door.

There was no cupboard behind it.

A vast room waited on the other side, lit by hanging lamps and filled with shelves that rose beyond sight. Objects gleamed in glass cases. A tree grew through the center of the stone floor, its branches disappearing into a ceiling painted with stars.

Three people stood beside a long table.

A broad man in a worn jacket held a sword as though he’d been born with it in his hand. A red-haired woman was writing equations across several sheets of paper at once. A younger man leaned against the table, examining a gold watch that Alex suspected had belonged to someone else a few minutes earlier.

All three turned toward the open cupboard.

Alex looked behind him. The empty flat remained unchanged.

“That isn’t possible,” he said.

Flynn smiled. “You’ll be saying that a lot.”

A bullet struck the wall beside the cupboard.

Baird shoved Alex through the doorway. Flynn followed. Baird crossed last and pulled the door closed.

The cupboard vanished.

A heavy wooden door stood in its place.

Alex moved toward it and opened it immediately. A brick wall was on the other side.

He shut it and looked at Flynn. “Where are we?”

“The Library.”

“You said you were a librarian.”

“I am.”

“You didn’t mention this.”

“I mentioned alternate dimensions.”

“That sounded like nonsense.”

“It still might,” the younger man at the table said. His accent was Australian. “You get used to it.”

The broad man lowered the sword but didn’t put it away. “Who’s the kid?”

“Alexander Rider,” Flynn said. “Fourth surviving candidate.”

“Alex.”

Baird holstered her gun. “He’s sixteen.”

The red-haired woman stopped writing.

The Australian straightened.

The broad man looked at Flynn. “You recruited a kid?”

“I didn’t recruit anyone. The Library selected him.”

“The Library needs its head examined,” Baird said.

“The Library doesn’t have a head.”

“It has something I can yell at.”

The room trembled faintly.

Dust fell from one of the highest shelves.

Baird looked up. “Good. It can hear me.”

Flynn gestured toward the others. “Alex, this is Cassandra Cillian, mathematician and scientist. Jacob Stone, art historian, archaeologist, architect, and several other things he pretends not to be. Ezekiel Jones, professional thief and enthusiastic narcissist.”

“World-class thief,” Ezekiel corrected.

Stone pointed the sword toward the gold watch in his hand. “Who did that belong to?”

Ezekiel examined the face. “Someone who wasn’t paying enough attention.”

Cassandra approached Alex, studying him with open curiosity that didn’t seem hostile. “The Library selected you recently.”

“So I’ve been told.”

“The rest of us received invitations ten years ago.”

“I was six.”

“Yes, that would’ve made an interview difficult.” Her eyes unfocused briefly. “Your name wasn’t there when Charlene last checked the ledger thirteen days ago. The ink is chemically new, but the paper has aged as though the entry has always been present. The Library rewrote the page instead of adding you normally.”

Alex looked at Flynn. “Does she always do that?”

“Yes,” Flynn and Stone said together.

Cassandra smiled apologetically. “Sometimes I see connections.”

“Sometimes she sees every connection,” Stone said.

Alex’s gaze moved to the sword in Stone’s hand. It had a wide blade, an ornate hilt, and a faint blue glow along its edge.

“Your sword’s glowing,” he said.

Stone looked down at it. “Flynn says it belonged to Joan of Arc.”

“It didn’t belong to Joan of Arc,” Flynn said. “It was carried by Étienne de Vignolles during the Loire campaign.”

Stone frowned. “You said Joan of Arc.”

“I said Joan of Arc was standing nearby.”

“Those are different statements.”

“Historically, proximity is often mistaken for ownership.”

Alex noticed a second sword resting in a low block of stone near the central table. Its blade was narrower and brighter than the one Stone held, and it shifted slightly as Flynn passed.

“And that one?”

“Excalibur,” Flynn said.

Alex looked at him.

“Cal,” Flynn corrected. “He’s sensitive.”

The sword tilted toward Alex as though listening.

Ezekiel looked at Alex. “You planning on joining this?”

“No.”

“Smart.”

“You’re still here.”

“I like the building.”

A woman’s voice came from behind Alex. “Mr. Carsen.”

Everyone except Flynn reacted.

Alex turned.

A middle-aged woman stood at the base of a staircase, dressed in a dark suit with her hands clasped in front of her. Her expression suggested Flynn had disappointed her before breakfast and continued doing so at regular intervals.

An elderly man stood beside her. He wore a bow tie and a cardigan and seemed considerably more amused.

Flynn’s shoulders dropped. “Charlene.”

“You brought another candidate into the Library.”

“The alternative was leaving him in a flat with one Brotherhood assassin unconscious and at least one more shooting through the door.”

“I had it handled,” Alex said.

Baird looked at him. “You were escaping through the floor.”

“That was handling it.”

Charlene descended the final steps. “The candidate ledger hasn’t accepted a new name during an active Librarian’s tenure in over two thousand years.”

“That seems relevant,” Baird said.

“It’s irregular.”

“He’s a minor.”

“That is also irregular.”

“Can the Library remove him from the list?”

The elderly man answered. “The Library chooses according to capacity, not age.”

Alex looked at him. “Then the Library is wrong.”

The man’s eyebrows lifted.

Alex continued. “I’m not applying for a job, I’m not interested in joining a secret organization, and I don’t care how old the paper is. Remove my name.”

“The ledger can’t be altered by us,” Charlene said.

“It added me.”

“The Library added you.”

“Tell it to change its mind.”

A book shot from a nearby shelf and landed on the table with a bang.

The cover opened.

Words appeared across the first page in dark ink.

CANDIDATE STATUS: ACTIVE

Alex stared at it.

Ezekiel leaned over the table. “It likes you.”

“I’m beginning to understand why people want to destroy this place.”

The elderly man laughed.

Charlene gave him a disapproving look. “Judson.”

“What? He has a point.”

Baird moved beside Alex. “He hasn’t accepted the invitation.”

“Acceptance isn’t required for someone to remain a potential candidate,” Charlene said. “Mr. Stone, Ms. Cillian, and Mr. Jones all declined to attend their interviews. Their names remained in the ledger.”

“And now someone is trying to kill them,” Alex said.

The humor left Judson’s face.

“Yes,” he said. “That’s why you can’t simply walk away.”

“I’ve walked away from worse.”

Flynn set Alex’s invitation on the table. “The man in your flat belonged to the Serpent Brotherhood. They have a copy of the candidate list, and they’ve already removed everyone else who appeared on it. You, Stone, Cassandra, and Ezekiel are the only known candidates still alive. Your name appeared after the killings began, which is why they came for you last.”

Cassandra’s pen stopped moving.

Stone lowered his sword.

Ezekiel’s expression became still, the careless amusement gone so quickly that Alex wondered how much of it had been real.

“How many?” Alex asked.

“Twenty-seven dead,” Baird said. “Three of them were killed while we were locating Cassandra and Stone.”

“You knew they were coming for me.”

“We found your name seven minutes before we opened the Door to London.”

“You found the address.”

“The Library did,” Flynn said.

Alex looked at the invitation lying on the table.

The paper knew his full name. It had found a flat that wasn’t registered to him, behind an identity he’d constructed less than two weeks ago.

He hated it immediately.

“Why are they killing the candidates?” Alex asked.

“Their leader is a man named Dulaque,” Flynn said. “He wants to make sure the Library has no one left to replace me. His lieutenant, Lamia, is coordinating the murders.”

“Why now?”

“We don’t know yet. One of the victims was trying to reach the Library about something he’d found.”

Alex glanced toward the others. “You’re the current Librarian.”

“Have been for ten years.”

“And they were candidates for your position?”

“Potential replacements. Historically, the Library chooses one Librarian at a time.”

“Then why keep three former candidates active and add me now?”

Flynn spread his hands. “That’s an excellent question.”

“The Library believes something is coming,” Judson said quietly.

The lamps above them dimmed.

For the first time since entering, Alex became aware of the scale of the room beyond the visible shelves. Corridors branched away between artifacts and books. Staircases climbed into shadows. The Library didn’t feel empty, but it felt watchful.

He’d entered buildings designed to intimidate people before. MI6 preferred clean walls, controlled lighting, and silence. Scorpia used stone, ceremony, and the suggestion that everything around them had survived longer than the person being addressed.

The Library didn’t need to try.

It was larger than all of them, and it knew Alex’s name.

He disliked that more than intimidation.

Baird placed a file on the table. “The victims weren’t all killed the same way, but the weapons had connections to Arthurian legends. A spearhead associated with Camlann. A dagger forged from metal taken near Glastonbury. Crossbow bolts carved from an oak believed to have grown outside Tintagel.”

Stone opened the file. “They weren’t choosing weapons at random.”

“The last victim was Professor Jonas Sheir,” Baird continued. “He called Flynn shortly before he was killed outside the Library’s public entrance. He said he’d found what the Brotherhood was searching for.”

She opened the file to a photograph of a folded museum brochure recovered from Sheir’s coat. A medieval painting filled the visible page, showing a dark metal crown above a line of armored figures.

Stone leaned closer. “The Crown of King Arthur.”

Flynn’s attention sharpened. “Merlin forged the crown so Arthur could control the magical weapons he needed to build Camelot. If the Brotherhood wants to return magic to the world, the crown would let them control what comes back.”

Cassandra pulled the map closer. “Twenty-seven deaths in eleven countries. If the murder locations correspond to the artifacts—”

Alex took several crime-scene photographs from the file and spread them across the table. He examined the bodies, the surrounding ground, and the evidence markers before comparing them to the written reports.

“These aren’t all the murder sites,” he said.

Baird leaned closer. “What are you seeing?”

Alex placed one photograph beside its report. “This man was found beside a road, but most of his blood was inside the abandoned car half a kilometer away. He was killed there and moved afterward.”

He selected another image. “The woman in Prague was dragged. Her shoes are clean, but there’s mud across the back of her coat, and the report mentions blood beneath a railway arch two streets from where they found her.”

Stone examined the photograph. “He’s right.”

Alex found a third discrepancy, then moved the corresponding markers on the map to the locations where the victims had actually been attacked.

Cassandra stared at the revised arrangement. Her pencil began moving across the paper, connecting the points in the order of the deaths.

“They moved the bodies to hide the exact coordinates,” she said. “The murders happened along old ley intersections.”

Lines spread across the map, curving through Europe until they formed a narrow crown.

Stone recognized it first. “Corona Borealis.”

“The Northern Crown,” Flynn said. “Usually associated with Ariadne, but medieval Arthurian scholars used the constellation as a cipher for objects connected to Camelot.”

Alex studied the pattern. “They weren’t only removing possible replacements for Flynn.”

“They used the deaths to power a locating spell,” Cassandra said. “Candidate blood at twenty-seven magical intersections. Each point narrowed the search area.”

She extended several measurements from the crown. The lines converged over southern Germany, covering a wide section of the Black Forest.

Flynn’s expression darkened. “The Brotherhood killed the people most likely to find the crown and used their deaths to locate the region where it was hidden.”

“But not the exact site,” Alex said.

Cassandra shook her head. “The convergence area is still hundreds of square kilometers. They needed another clue.”

Everyone looked toward the brochure.

Ezekiel leaned over the table. “That painting’s in the Munich Museum of History and Art.”

Stone glanced at him. “You know the painting?”

“I cased the building last month,” Ezekiel said. “The painting’s a fake, the frame’s bolted into a support beam, and the security around it is much better than the art deserves.”

At Flynn’s request, the Library produced a current image of the painting, the frame, and the museum’s architectural plans. Cassandra found a sequence engraved along the inner edge of the frame. Stone translated the Latin worked into the painted border, while Ezekiel marked the camera positions and structural walls from memory.

Alex studied the plans beside the photograph. “If the frame can’t be moved, its position in the building is part of the cipher.”

Cassandra’s pencil stopped. Then it began moving quickly, combining the engraved sequence with the dimensions of the rooms surrounding the painting and the convergence area from the murder pattern. Stone supplied the final translation, and the broad section of forest narrowed to a single point.

“Near a megalithic site documented in 1732 and later buried by a landslide,” Cassandra said.

Stone shook his head. “It wasn’t buried. The location was suppressed. There are sketches in a seventeenth-century manuscript attributed to Elias Ashmole.”

Flynn pointed toward him. “Exactly.”

“I haven’t finished.”

“You were going to say the stones were built around something older.”

Stone’s mouth tightened. “I hate when you do that.”

Baird tapped Professor Sheir’s photograph. “His office was stripped after his death. If the Brotherhood found the brochure or the museum records before we did, they may already have part of the cipher.”

“They would’ve learned the region from the murders,” Alex said. “Sheir found the clue that narrows it to the entrance.”

Flynn gathered the photographs and looked down at the coordinates. “The Brotherhood killed the candidates because they were the people most likely to find the crown before they did. Professor Sheir got close enough to leave us the final clue, which means we may still be able to reach it first.”

“You may,” Ezekiel said. “I’m leaving.”

Charlene gave him a flat look. “Through which door?”

“The one marked exit.”

“There is no door marked exit.”

“There should be.”

Baird looked at the three adult candidates. “The Brotherhood knows who you are. Until we stop them, staying together is safer than sending any of you back outside.”

“Then we stay here,” Stone said.

Flynn shook his head. “The clues were designed to require several kinds of knowledge. The people on the candidate list were the ones most likely to solve them, and the Brotherhood knows the surviving candidates are together. They’ll assume we’re moving for the crown. I need all of you.”

“You need them,” Baird corrected. “Alex stays here.”

Alex folded the map. “I don’t remember needing your permission.”

“You’re sixteen.”

“I noticed.”

“You were shot at less than an hour ago.”

“I wasn’t hit.”

“And you reacted as if it happens regularly.”

“It has.”

Baird’s gaze settled on his face. “How regularly?”

Alex put the map down. “Doesn’t matter.”

“It matters to me.”

“You met me less than an hour ago.”

“And in that time, I watched you fight a trained assassin and treat being targeted by an ancient cult like an inconvenience. You’re not going into a forest to recover a magical weapon.”

“It’s a crown.”

“That isn’t the point.”

“The Brotherhood found me through your list. They know my face and where I was staying, and I’m not waiting behind with people I don’t know while everyone else decides what happens to me.”

Baird’s expression shifted. “I’m trying to keep you alive.”

“By making the decision for me.”

She held his gaze, but Flynn spoke before she could answer. “Leaving one targeted candidate behind while the rest of us take the Back Door to Germany may not actually be safer.”

Baird looked at him. “You’re not helping.”

“I rarely do on purpose.”

She studied Alex for another moment, then handed him one of the communication units from her pocket. “You stay beside me.”

“That sounded different a minute ago.”

“I changed my mind. Try not to make me regret it.”

Flynn led them to a freestanding wooden door near the edge of the chamber. He explained to Alex that the Back Door wasn’t a fixed entrance so much as a way of turning almost any door into a passage elsewhere. With the Library’s key and a destination in mind, Flynn could open it nearly anywhere in the world.

He fitted the brass key into the lock and turned it.

Cold air swept into the Library as the door opened onto a snow-covered forest.

Alex stepped through and sank ankle-deep into the snow. 

The air was colder than London, sharp enough to burn the back of his throat. Pines crowded the hillside ahead, their branches heavy beneath white, while moonlight filtered through a layer of thin cloud.

Stone emerged behind him, followed by Cassandra, Ezekiel, Flynn, and Baird. The Door stood upright among the pines without a wall around it.

Baird closed it. The entire frame vanished.

Alex walked around the place where it had been.

There were no tracks except theirs.

“You believe in magic yet?” Ezekiel asked.

“I believe the door moved us.”

“To Germany.”

“Probably.”

Ezekiel laughed. “You’re stubborn.”

“You admitted that watch was stolen.”

“It was a very attractive watch.”

Baird distributed small communication devices to Stone, Cassandra, and Ezekiel. She took the unit she’d already given Alex, clipped it beneath his collar before he could object, and tested the channel. “You stay within sight.”

“I heard you the first time.”

“I’m making sure.”

“Do you usually guard people by announcing it every thirty seconds?”

“I usually don’t have to remind a sixteen-year-old that being capable doesn’t make him bulletproof.”

“I know that.”

Baird glanced at him. “Your behavior suggests otherwise.”

Stone lifted one hand. “For the record, some of us have field experience.”

“Bar fights don’t count.”

“They count to the other guy.”

“I’ve evaded international law enforcement,” Ezekiel said.

“That isn’t field discipline.”

Cassandra adjusted her scarf. “I completed a wilderness first aid course.”

Everyone looked at her.

“It was online.”

Baird pinched the bridge of her nose.

Flynn had already started uphill. “The crown should be less than two kilometers east.”

Alex followed the tracks Flynn left in the snow. “How do you know?”

“The stars.”

“The sky’s overcast.”

“The moss.”

“It’s covered in snow.”

Flynn glanced back. “The Library gave me a compass.”

Alex saw the brass instrument in his hand. “Why didn’t you say that?”

“I wanted to see how long you’d continue.”

The forest grew denser as they climbed. Stone and Cassandra discussed the possible age of the ruins. Ezekiel complained about his shoes. Baird ranged between the front and rear of the group, scanning the trees and repeatedly checking that Alex remained where she’d placed him.

Flynn stopped near the top of the ridge.

At first glance, the snow ahead looked undisturbed.

Alex studied the trees.

A branch had been cut at shoulder height to their left. Sap still glistened across the pale wood. Several needles had been crushed into the snow near a trunk, and shallow sweep marks remained along the edges of a trail someone had tried to erase.

“Someone covered their tracks,” Alex said.

Baird moved beside him. “How many?”

“At least six. They brushed out the deeper prints, but I can still see six different tread patterns along the edges.”

Flynn looked toward the ridge. “The Brotherhood.”

“Can they reach the crown without us?” Stone asked.

“If they could solve the mechanism inside, they would’ve gone in already.”

Ezekiel took two steps backward. “Then we don’t solve it for them.”

A throwing blade struck the tree beside his head.

Baird drew her gun.

Figures dropped from the branches.

The first attacker landed between Flynn and Cassandra. Stone caught him across the ribs with one forearm before he could raise his sword. Baird fired at a second man advancing through the trees, forcing him behind cover.

Alex ducked as a blade passed over him. The attacker who had thrown it came through the snow quickly, carrying a curved sword in both hands.

Alex picked up a fallen branch and drove the broken end into the man’s face.

The attacker recoiled. Alex stepped inside the reach of the sword, caught the man’s elbow, and sent him into a tree. His forehead struck the trunk with a hollow crack.

A hand closed around the back of Alex’s coat.

Baird pulled him aside as another sword cut through the place where he’d been standing.

She fired twice, and the attacker fell.

“I said beside me.”

“I was three meters away.”

“That isn’t beside me.”

Ezekiel slid through the snow, caught a dropped knife, and threw it with surprising accuracy. The hilt struck a Brotherhood soldier in the temple.

Stone stared at him. “You could’ve used the sharp end.”

“I’m a thief, not a murderer.”

The ground shook beneath them.

Cassandra stood near the ridge with both hands pressed to her temples. Her eyes tracked something none of the others could see.

“The pattern,” she said. “Their positions match the outer points of the crown.”

Alex looked around. The attackers had spread into an arc, but none of them was trying to close the distance.

“They’re not surrounding us,” he said. “They’re keeping us in the center.”

Flynn saw it. “Move!”

Baird drove one attacker out of position. Stone tackled another downhill. Alex caught Cassandra’s sleeve and pulled her toward the trees as a line of blue light burned across the snow beneath their boots.

The entire ridge lit up.

Stone pillars rose from beneath the ground.

Snow and frozen earth slid away as twelve standing stones emerged around them. Symbols glowed across their surfaces, lines interlocking in a script Alex didn’t recognize.

The Brotherhood soldiers retreated beyond the rising stones.

The center of the circle split open.

A stone staircase descended into darkness.

Flynn looked delighted. “Found it.”

Baird stared at him. “They used us to open the site.”

“Yes.”

“And you’re pleased.”

“I can be pleased and concerned at the same time.”

A woman stepped between the trees above the ridge. She had dark hair, a black coat, and the calm confidence of someone who expected the fighting to end when she arrived. A sword hung at her side.

“Flynn Carsen,” she said.

Flynn’s delight disappeared.

“Lamia.”

Her gaze passed over Baird, Stone, Cassandra, and Ezekiel before stopping on Alex.

“The child wasn’t in our original records.”

Alex looked at Flynn. “I’m hearing that a lot.”

“The Library has become desperate,” Lamia said. “Selecting fighters instead of scholars.”

Baird shifted between them. “He’s sixteen.”

“And yet he’s already put two of my men on the ground.” Lamia’s gaze returned to Alex. “Whatever he is, he isn’t only a schoolboy.”

Alex kept his expression still.

Flynn looked at him, but there wasn’t time for the question forming on his face.

Lamia drew her sword.

The Brotherhood attacked again.

Flynn ran toward the stairs. “Get the crown!”

Baird swore and followed him.

Alex caught the sword arm of the nearest attacker and struck him beneath the jaw. Stone moved beside him, using a dropped staff with practiced force. Ezekiel disappeared completely, which Alex suspected was intentional rather than magical.

Cassandra stood at the entrance to the staircase, staring down into the dark.

“I can see the mechanism,” she called. “It’s moving.”

“Then move with it,” Stone said.

They descended.

The staircase rotated beneath their feet. Walls slid across the passage, closing routes and opening others. Blue light traveled through symbols carved into the stone.

Flynn and Baird were already ahead. Alex followed Cassandra through a narrowing gap. Stone came behind him, barely clearing the wall before it sealed. Ezekiel appeared on the other side.

“How did you get there?” Stone demanded.

“I took a shortcut.”

“There wasn’t another passage.”

“Not with that attitude.”

The corridor opened into a circular chamber.

The crown rested on a stone pedestal in the center. It was simple compared to the crown jewels Alex had seen during school trips: a narrow band of dark metal set with one red stone. Age had blackened most of the surface.

Flynn approached it slowly.

Baird covered the entrance.

Cassandra’s eyes moved across the floor. “Pressure plates.”

“Magical or mechanical?” Alex asked.

“Yes.”

Stone crouched beside the nearest tile. “The pattern is based on a medieval cosmological map.”

“It’s older than that,” Flynn said. “The design was reused during the Carolingian period.”

“Can we argue after we aren’t surrounded by assassins?” Baird asked.

Ezekiel stepped past all of them.

Alex saw his foot move toward a tile crossed by an almost invisible strand.

“Stop.”

Ezekiel froze.

Alex pointed toward the floor. “Wire.”

Ezekiel looked down. The filament ran from the edge of the tile into a narrow channel carved beneath the pedestal.

Flynn crouched to examine it. “Part of the original mechanism.”

“It’s attached to the crown,” Alex said. “Lifting it without releasing the tension triggers something.”

Stone studied the carvings surrounding the tile. “The symbols describe the burial of a king beneath a fallen mountain.”

“Probably literal in this case,” Flynn said.

“Then let’s avoid testing it,” Baird replied.

Stone and Cassandra began tracing the pressure plates and translating the instructions worked into the floor. Flynn supplied historical context while Baird watched the entrance for the Brotherhood.

Alex moved around the outer edge of the chamber, following the narrow channel carrying the bronze filament away from the pedestal.

“What are you looking for?” Stone asked.

“A way for whoever placed the crown here to leave without setting off the trap.”

He found a seam behind one of the carved panels. Dust had gathered along most of its edges, but the stone near the floor remained clean where the mechanism had shifted over the centuries.

“Secret door?” Ezekiel asked, coming beside him.

“Probably.”

“I’ll open it.”

“I found it.”

“You want a medal?”

“I want you to move.”

Ezekiel grinned. “You’re almost as difficult as I am.”

“That isn’t a compliment.”

“It is from me.”

Together, they pressed the concealed catches. The panel slid aside, revealing a cramped passage running behind the chamber wall. An iron lever waited just inside, connected by cables to the pedestal and the main entrance.

Alex followed the lines with his eyes. “The lever drops the entrance slab. Whoever designed this place could remove the crown, seal the chamber behind them, and leave through here.”

Baird looked toward the distant sound of fighting in the corridor. “Can we use it?”

“Once Stone and Cassandra disarm the pedestal.”

Three minutes later, Cassandra guided them across the floor while Stone held the crown steady. Flynn replaced it with a fragment of stone of nearly equal weight, and Ezekiel carefully unhooked the bronze filament.

They withdrew into the concealed passage. As Lamia’s soldiers reached the chamber, Alex pulled the lever.

The stone slab dropped across the main entrance.

A sword struck the other side.

Baird turned down the hidden passage. “Move.”

The passage climbed toward a ruined chapel beyond the henge. Flynn used the Library key on its warped door, and they were gone before Lamia’s soldiers broke through the slab.

The Library greeted them with music.

Trumpets sounded from somewhere overhead as Flynn carried the crown through the main chamber. Lamps brightened one after another, and several books opened along the shelves as though applauding.

Alex flinched when a suit of armor raised its sword.

Ezekiel noticed. “Magic.”

“Automation.”

“The armor doesn’t have a motor.”

“You checked?”

“I tried to steal it.”

Stone looked at him. “Of course you did.”

Charlene met them near a wide stone table. Judson stood beside her, smiling as Flynn placed the crown beneath a glass dome.

“The crown of King Arthur,” Flynn announced. “Recovered through scholarship, mathematics, theft, military strategy, and a concerning disregard for personal safety.”

Baird looked at Alex. He ignored her.

Charlene examined the crown. “The wards will need to be reset.”

“I can help with the mathematical seals,” Cassandra said.

“After I finish cataloging it,” Charlene replied.

Stone moved toward a book Flynn had left open. Ezekiel wandered toward the artifact cases despite Charlene’s warning look.

The group relaxed by degrees.

Alex didn’t. The route from the Black Forest had closed behind them, and no one had followed. Everything suggested the immediate danger had passed.

Cassandra kept touching the side of her head. She’d done it in the forest as well, usually after using whatever ability allowed her to see patterns. The movement seemed practiced, hidden beneath adjustments to her hair.

Alex watched her leave the table.

She crossed toward the rear corridor without telling anyone.

Flynn and Judson were discussing the crown’s history. Baird had begun examining a cut across Stone’s hand. Ezekiel was attempting to open a locked cabinet.

Alex followed Cassandra.

She moved quickly once she passed the first row of shelves. The corridor beyond curved through a collection of statues and darkened display cases. Alex stayed far enough behind that she shouldn’t hear him.

Cassandra stopped in a narrow passage lined with doors and pressed a small black key against the blank lock plate on the nearest one.

Alex touched the communication unit beneath his collar. Only static answered him.

A woman’s voice came through the other side. “Are you in position?”

“The crown is in the main chamber.” Cassandra pressed one hand against her head. “You said no one would be hurt.”

“The candidates who survived are safe.”

“Your people tried to kill us.”

“They were instructed to frighten you into cooperating.”

“That man in Germany nearly cut Alex’s head off.”

“He failed.”

Cassandra’s voice shook. “You promised you could cure me.”

“We can.”

“Cure what?” Alex asked.

Cassandra spun around.

The door shuddered behind her.

Alex stepped out of the shadows. “Don’t open it.”

For one second, Cassandra looked as though she might listen.

Then pain crossed her face. She turned the black key.

The door flew inward. Lamia caught Alex across the chest with one forearm and threw him through a glass display case as Brotherhood soldiers poured into the Library.

By the time he forced himself upright, the main chamber had erupted into chaos. A warm line of blood ran from a cut near his hairline.

Serpent Brotherhood soldiers spread from the open door. Glass shattered. Books flew from shelves. Artifact cases opened and closed as the Library attempted to protect itself.

Cassandra stood beside Lamia near the open door, empty-handed.

Stone stared at her. “You let them in.”

“I didn’t know they were going to do this.”

“They murdered twenty-seven people!”

“They said they could help me.”

Lamia crossed to the central table, shattered the glass dome, and took the crown.

Baird fired toward the Brotherhood soldiers advancing along the stairs. Flynn drew a sword from beneath the table and met another attacker beside the tree.

A man lunged toward Alex. Alex caught a heavy book from the air and drove its spine into the man’s face. The book opened, pages whipping forward hard enough to knock the attacker backward.

Alex dropped it.

“Thank you,” he told the Library.

The book fluttered once and returned to its shelf.

Stone reached Cassandra, but two Brotherhood soldiers separated them. Ezekiel swung from the upper walkway on a length of red fabric, kicked one attacker over the railing, and landed badly beside Alex.

“I meant to do that.”

“You missed the table.”

“I adjusted.”

Lamia walked toward the stone where Excalibur rested.

The sword pulled itself free.

It hovered in front of her, blade glowing blue.

Flynn stopped fighting.

“Cal,” he said. “Don’t.”

Lamia placed the crown on her head.

Excalibur trembled.

Then the sword turned toward Flynn.

Baird saw it first. “Move!”

Flynn twisted aside.

The blade changed direction in midair and struck him through the stomach.

Everything stopped.

Excalibur pulled itself free.

Flynn looked down at the blood spreading across his shirt. His knees folded.

Baird caught him before he hit the floor.

Alex moved toward them, but a line of Brotherhood soldiers closed across the chamber. Stone grabbed Alex by the shoulder and dragged him behind the stone table as arrows struck the floor.

“What do we do?” Ezekiel asked.

A deep bell rang.

Judson stood on the staircase above them with Charlene beside him. Light poured from the walls around them.

“The Library must be severed,” Charlene said.

Flynn lifted his head weakly. “You can’t.”

“If the Brotherhood takes control, everything stored here will become theirs.”

Judson looked at the candidates gathered below. “The Back Door will remain open for another thirty seconds.”

Stone looked toward Cassandra.

She stood beside Lamia, crying silently.

“Come with us,” he shouted.

Cassandra took one step.

Lamia caught her arm.

The Library shook.

Shelves folded inward. Corridors disappeared. The stars painted across the ceiling began moving, turning faster until the entire sky spiraled above them.

Baird pulled Flynn upright.

“Door!” she ordered.

Ezekiel ran toward the nearest archway. Stone followed, helping Alex over the shattered remains of a case.

Alex looked back.

Judson and Charlene remained on the stairs.

“You’re coming,” he said.

Judson smiled.

“Someone has to turn out the lights.”

Alex knew farewell when he heard it.

He hated adults who tried to make it sound gentle.

The Back Door opened onto a forest washed in afternoon light.

Ezekiel crossed first. Stone pushed Alex through after him. Baird carried most of Flynn’s weight behind them.

Excalibur flew across the chamber toward the closing Door.

The sword passed through.

Lamia and Cassandra didn’t.

The Door slammed shut.

For one second, the Library remained visible around its frame. Judson raised one hand. Charlene stood straight beside him as the shelves and staircases vanished into white light.

Then the frame became an ordinary wooden door standing among Oregon pines.

The Library was gone.

A shotgun clicked behind them. “Identify yourselves.”

Alex turned.

An older man stood near a low stone building half-hidden among the trees. His suit was old-fashioned, his hair white, and his expression suggested he regarded the arrival of bleeding strangers as a personal inconvenience.

Flynn managed to lift his head. “Jenkins.”

The shotgun lowered.

“Mr. Carsen.” Jenkins looked at the blood covering Baird’s hands. “You appear to have misplaced the Library.”

“Temporarily.”

“You’ve been here less than a minute and have already lied to me.”

Flynn tried to smile.

He collapsed.

Jenkins opened the building.

The Library Annex contained fewer shelves than the main Library, although fewer still meant thousands. Long worktables occupied the center of the room. Mechanical devices, maps, and half-assembled artifacts covered nearly every surface.

They placed Flynn on one of the tables.

Baird cut his shirt away from the wound. Alex stood opposite her, applying pressure where she directed. Blood soaked through the first cloth and then the second.

“It isn’t clotting,” Alex said.

“Excalibur,” Jenkins replied. “Wounds inflicted by the sword don’t heal.”

“Then why are we pressing on it?”

“It slows the bleeding.”

“Barely.”

Baird looked at Jenkins. “Fix him.”

“I can’t.”

“You run a magical library.”

“An Annex. The distinction is currently critical.”

Stone paced near the table. Ezekiel had stopped making jokes. He stood beside one of the shelves, staring at Flynn’s blood on his hands.

Alex increased the pressure.

Flynn’s eyes opened.

“You have terrible bedside manner,” he murmured.

“You’re bleeding to death.”

“Yes, I’d worked that out.”

Jenkins disappeared into a storeroom and returned with a narrow bottle. A small amount of amber liquid remained at the bottom.

“Bathsheba’s Oil of Healing,” he said. “One dose.”

Baird took it. “Will it close the wound?”

“No. It may give him a day.”

Flynn drank.

The bleeding slowed beneath Alex’s hands. It didn’t stop, but the blood no longer poured through the cloth as quickly.

Baird bandaged him.

Stone moved toward Jenkins. “Cassandra betrayed us.”

“I gathered that from the absence of the crown and the presence of Excalibur.”

The sword lay on another table.

Its glow had faded, and it rested unnaturally still against the wood.

“It’s dying,” Flynn said.

Alex looked at him. “It’s a sword.”

“It’s Cal.”

“Does naming it improve the diagnosis?”

Excalibur lifted weakly from the table and struck Alex’s arm with the flat of its blade.

He stared at it.

Ezekiel gave a short laugh. “It doesn’t like you.”

“I don’t like it.”

The sword hit him again.

“Stop.”

Excalibur dropped onto the table.

Jenkins looked between them. “Interesting.”

“It stabbed him,” Alex said. “It doesn’t get to be offended.”

“The crown compelled it,” Jenkins said. “Being torn through the Door while the Library severed itself damaged most of its remaining magic.”

“It still stabbed him.”

Flynn shifted against the table. Pain crossed his face before he covered it with another strained smile.

“Lamia has the crown and Cassandra. Excalibur followed us through the Door, but the crown can call and control it from a distance. Dulaque wanted the Library removed because the Library kept magic under control.”

“The ritual isn’t finished,” Stone said.

“It’s barely started. The Brotherhood still has to reunite Excalibur with the Stone of Arthur, and leaving the sword here won’t stop the crown from summoning it.”

Ezekiel frowned. “The stone in the German chamber?”

“Wrong stone,” Jenkins said. “That was the crown’s resting place. The Stone of Arthur has been hidden beneath London since the end of the Roman occupation.”

“Where beneath London?” Alex asked.

Jenkins looked at him for the first time properly.

His gaze moved over Alex’s wet clothes, the knife visible above his boot, the fading bruises beneath one sleeve, and the blood on his hands.

“Who are you?”

“Alex.”

“He’s the fourth candidate,” Flynn said.

Jenkins’s eyebrows rose. “That one?”

“You know about me.”

“I know the Library added a name. I assumed the ink had developed delusions.”

“The Library has poor judgment.”

“So I’m learning.”

Baird secured the final bandage. “The Stone is beneath London. Where?”

“The location has been protected by the British Crown for centuries. We need the Star of Marrakesh to find it.”

Stone looked toward the shelves. “You have it here?”

“It’s displayed beside the Crown Jewels in the Tower of London.”

Alex almost laughed.

Jenkins noticed. “Is there a problem?”

“You expect us to steal an artifact from the Jewel House.”

“Borrow.”

Ezekiel pushed away from the shelf. “Finally, something reasonable.”

Baird pointed toward Flynn. “He isn’t going anywhere.”

“I have approximately twenty-two hours to live,” Flynn said. “I’d rather use them.”

“You can barely sit up.”

“Give the oil time.”

“You’re not going.”

Flynn looked toward Alex. “She’s very controlling.”

“She’s right.”

Baird glanced at him, surprised.

Alex washed Flynn’s blood from his hands in a basin beside the worktable.

“She’s also wrong about me.”

Her expression hardened again. “You’re staying here.”

“The Brotherhood knows my name, my face, and at least one address. They’ve just removed the only place you considered safe.”

“Which is why you’re staying in the Annex.”

“With him?”

Jenkins looked offended. “I am standing here.”

“You didn’t notice the main Library disappear until we arrived.”

“The main Library frequently moves without consulting me.”

“I know a service route beneath the Tower’s outer wall and enough about the security layout to get us close.”

Stone stared at him. “How?”

Alex dried his hands. “A former employer made me memorize the emergency plans for several royal sites before canceling the operation. The information’s old, but the route should still exist.”

“You’re sixteen,” Stone said. “You shouldn’t have a former employer who gives you royal security plans.”

“I’m aware.”

Baird stepped closer. “You don’t have to prove you’re useful.”

He met her eyes. “I’m not proving anything.”

The room became quiet.

Alex had heard adults tell him he didn’t have to do something before. They usually meant he did have to do it, but they wanted him to pretend the decision had been his. Baird sounded different, which made it harder to dismiss her.

She wasn’t asking him to prove he was useful.

She seemed to wish he weren’t.

“The Brotherhood came after me because your Library chose me,” he said. “I’m finishing this.”

Baird studied his face.

Then she looked at Jenkins. “Does the Annex have body armor in his size?”

Alex sighed.

Before Jenkins opened the Back Door, he sealed Excalibur inside a warded cabinet. The sword struck the inside once, then fell silent.

The Tower’s wards prevented the Back Door from opening inside the complex, so Jenkins anchored it to a maintenance room near the river. From there, Alex led them into the service passage beneath the outer wall.

Ezekiel disliked Alex’s route into the Tower because it didn’t involve enough stealing.

“It’s the Tower of London,” he whispered as they crossed a narrow maintenance passage beneath the outer wall. “We’re surrounded by centuries of accumulated treasure, and you’ve brought us through a drain.”

“It isn’t a drain.”

“There’s water.”

“Condensation.”

“It smells like a drain.”

Stone moved behind them, carrying the equipment Jenkins had assembled to remove the Star of Marrakesh from its setting without triggering the magical protections around it. Baird came next, with Flynn leaning against her shoulder despite repeated claims that he could walk unaided.

The oil had restored some color to Flynn’s face. It hadn’t stopped the wound. Every few minutes, his hand returned to his side, pressing against the bandage beneath his coat.

Alex led them to the metal access panel at the end of the passage.

The lock was newer than the one shown in the plans.

Ezekiel crouched beside him. “Need help?”

“No.”

Alex examined the lock while Ezekiel ran his fingers along the edge of the panel.

“There’s an alarm,” Alex said.

“Not anymore.”

Ezekiel held up a disconnected wire.

Alex glanced at him, then slid a pick into the lock. A few seconds later, the mechanism clicked open.

They emerged in a service corridor beneath the public section of the Tower. The building had closed hours ago, but guards remained at every major junction. Cameras covered the stairs and display areas.

An electronic lock blocked the next door. Alex watched the corridor while Ezekiel connected a thin cable from Jenkins’s kit to the reader.

“You said this route avoided the difficult security,” Ezekiel whispered.

“I said it got us beneath the wall.”

“That’s not the same thing.”

“I know.”

The reader flashed green.

Ezekiel grinned and opened the door.

Flynn looked between them. “I’m beginning to regret introducing you.”

Stone shook his head. “They would’ve found each other eventually.”

The Jewel House was dark beyond the emergency lighting. Glass cases reflected narrow strips of green. The Crown Jewels gleamed beneath carefully controlled lights in the central displays.

Ezekiel stopped.

Alex caught the back of his jacket. “We’re here for one artifact.”

“I’m appreciating history.”

“You’re calculating camera angles.”

“I can do two things.”

Stone identified the display holding the Star of Marrakesh, an emerald set alone on a dark velvet stand. Jenkins’s device looked like an ordinary metal clamp fitted with two copper wires and a dial.

“That’s magical?” Alex asked.

“Mostly electrical,” Flynn said. “Magic and science are much closer than either side likes to admit.”

Stone placed the device against the glass.

Cassandra would have known which frequency to use.

The absence settled across the group without anyone mentioning it.

Stone adjusted the dial slowly. A green line traced the edge of the case, and the front panel released with a soft click.

“John Dee used the Star to save Elizabeth I from a magical assassination,” he said.

“According to John Dee,” Flynn said.

“Your own catalog confirms it.”

“The catalog also says he exaggerated three times in the same paragraph.”

Baird watched the corridor. “Could both of you save the academic argument until after the theft?”

“Borrowing,” Flynn said.

Alex studied the security display beside the case.

A camera feed repeated every forty-eight seconds. Ezekiel had looped it, but one corner of the screen flickered at irregular intervals.

“Someone else is in the system.”

Ezekiel moved beside him. “That’s impossible.”

“You’re in it.”

“I’m better than everyone else.”

The display went black.

Emergency shutters slammed over every exit.

Red lights flooded the room.

A voice came through the speakers. “Alexander Rider.”

Alex knew the voice.

Lamia appeared on the security monitor.

She wore the crown. Cassandra stood behind her, pale and frightened, in a stone chamber lit by blue fire.

“You’ve been difficult to understand,” Lamia said. “The Library chose scholars, thieves, and soldiers before you. Now it sends a sixteen-year-old to solve its riddles, breach its defenses, and fight its battles.”

Baird moved closer to Alex.

He didn’t look at her.

“You murdered the other candidates,” he said.

“They would’ve replaced Flynn Carsen.”

“And I wouldn’t?”

“You don’t want the position.”

“That didn’t stop you trying to kill me.”

“The list had to be cleared. Your late addition created an inconvenience.”

Ezekiel worked on the access panel beneath the monitor.

Lamia smiled. “You’ve seen what the Library does. It gathers dangerous objects, hides them from the world, and appoints itself the only authority responsible enough to control them.”

Alex thought of MI6 files, Scorpia laboratories, and the people who claimed ownership of secrets because secrecy gave them power.

“You’re doing the same thing,” he said.

“We intend to give magic back.”

“To everyone?”

“To those capable of wielding it.”

“That sounds like everyone you approve of.”

Lamia’s smile faded.

Alex glanced toward Ezekiel.

Three seconds, Ezekiel mouthed.

“You said you could cure Cassandra,” Alex continued.

Cassandra looked toward the screen.

“We can,” Lamia said.

“Then why haven’t you?”

“She hasn’t completed her task.”

“She got you into the Library. She gave you access to the crown. She found the Stone.”

“She must finish the translation.”

Cassandra’s eyes narrowed.

Alex saw the change.

“She knows you’re lying now,” he said.

Lamia turned toward her.

Ezekiel restored the system.

The monitor went dark. The shutters rose.

Baird touched Alex’s shoulder. “You planned that?”

“I wanted her looking away from Cassandra.”

Stone lifted the loosened glass panel and removed the Star of Marrakesh from its stand.

It was an emerald the size of Alex’s thumb.

Flynn fitted it into the shallow brass compass Jenkins had packed and spoke a short phrase beneath his breath. Green light spread through the instrument, and a map of central London appeared across its face. A single point pulsed beneath Buckingham Palace.

“Buckingham Palace,” Stone said.

“Of course,” Alex replied. “There are tunnels beneath half of London, and it had to be the palace.”

The Tower alarms began sounding.

Ezekiel lifted the Star from the compass. “We can finish this somewhere we’re not about to be arrested for stealing.”

They retraced their route to the maintenance room, where the Back Door remained anchored.

They returned to the Annex, where Jenkins exchanged their dark clothes and equipment for formal wear that would let them pass through the diplomatic reception underway at Buckingham Palace.

Flynn found what he needed in the Annex’s wardrobe. Stone’s tuxedo fit well enough after Jenkins adjusted the sleeves. Ezekiel complained about the tie until Baird threatened to tighten it for him, while Baird chose a dark evening dress that concealed two knives and a compact firearm.

Alex’s suit fit perfectly over the protective vest Baird had insisted he wear.

He didn’t ask why Jenkins had clothing in his size.

Jenkins also provided identities placing all of them on the guest list. Alex’s identified him as the eighteen-year-old son of a junior Foreign Office minister. The name was plausible, the credentials professionally produced, and the photograph had been taken from one of Alex’s old school records.

Alex held the card toward him. “Where did you get this?”

“The Library maintains archives.”

“Delete them.”

“The Library is currently absent.”

“When it comes back.”

Jenkins gave him a long look. “I’ll submit the request.”

Once they were ready, Jenkins opened the Back Door at the nearest unwarded entrance to Buckingham Palace. From there, they joined the diplomatic reception already underway. 

The reception occupied several state rooms. Diplomats, politicians, military officers, and members of the royal household moved beneath chandeliers while a string quartet played near the windows.

Alex recognized several officials from rooms he’d never officially entered.

He avoided all of them.

Ezekiel took a glass from a passing tray. Baird removed it before he could drink. “I’m twenty-two.”

“You’re working.”

Stone glanced toward Alex. “How old are you supposed to be tonight?”

“Eighteen.”

“You don’t look eighteen.”

“I’ve been told.”

Flynn adjusted his coat over the blood seeping through his bandage. His face had become gray again.

Baird noticed. “We need to move.”

They crossed the reception and entered a private gallery through a door Ezekiel opened without breaking stride.

Alex disabled the alarm on the stairwell. Stone fitted the emerald back into Jenkins’s compass and used it to follow the magical trail through three lower levels.

The palace became older as they descended.

Modern plaster gave way to brick, then Roman stone. The air smelled of damp earth and smoke. Symbols had been painted across the walls in fresh blue pigment.

Alex crouched beside one without touching it. The blue pigment still shone beneath the light.

“Still wet.”

“They’re close,” Flynn said.

Voices came from the chamber ahead.

Cassandra stood in the center of a circular crypt, reading symbols carved across a stone arch. Lamia waited beside the Stone of Arthur, a dark block rising from the floor, with the crown already on her head. The space above the Stone remained empty, but blue light pulsed across its surface.

Dulaque stood behind them.

He looked older than Alex expected, with silver hair and an elegant dark coat. He held himself with the confidence of someone accustomed to waiting decades for his plans to succeed.

His gaze settled on Flynn.

“The Librarian,” he said. “Still alive.”

“Temporarily.”

“You won’t remain so.”

Dulaque looked toward the others, his attention lingering on Alex. “The unexpected candidate.”

Alex had been called worse.

Cassandra turned.

“Leave,” she said. “You don’t understand what will happen.”

“Magic returns to the world,” Flynn said. “Uncontrolled.”

“It’s already here. The Library keeps it locked away while people die who could be saved by it.”

Stone’s anger broke through. “They lied to you.”

“I know.”

“Then come with us.”

Cassandra pressed a hand to her temple. “The ritual has started. If I stop translating, the backlash could destroy everything above us.”

Hundreds of guests and staff remained in the palace above them.

Alex looked at the symbols around the room. “Can you change the translation?”

Cassandra’s eyes met his.

Lamia heard him. She drew her sword.

Baird intercepted her before she reached Cassandra.

Steel rang across the crypt. Stone engaged two Brotherhood soldiers beside the arch. Ezekiel disappeared into the shadows along the wall.

Flynn caught a Brotherhood sword Baird had knocked across the floor and walked toward Dulaque.

Dulaque drew his own blade.

Alex went to Cassandra.

“The symbols form an equation,” she said quickly. “Excalibur enters the Stone, the crown commands the sword, and the release travels through the old ley lines beneath London.”

“Can you reverse it?”

“Not after the sword enters.”

“Then delay it.”

Lamia drove Baird against a column. The crown glowed on her head, and a narrow blue seam began opening above the Stone.

Cassandra looked at the symbols.

Numbers and colors seemed to move behind her eyes. “I can alter the final line, but someone has to break the crown’s control.”

“How?”

“Magnetism. Arthur’s crown contains iron from a meteorite. A strong enough electromagnet could remove it.”

Alex looked around the crypt.

Copper wiring ran between the ritual lamps. An old iron pipe crossed the ceiling. Modern electrical cables had been added along one wall.

“Tell Ezekiel.”

“I don’t know where he is.”

Alex had seen him slip behind the third column when the fighting began. “He’s behind the third column.”

Cassandra looked.

Ezekiel leaned out. “How did you know?”

“You’re always where you shouldn’t be.”

Alex explained the plan.

Ezekiel stripped insulated copper from the ritual lamps while Cassandra changed three symbols in the final translation. Alex climbed the wall using the iron brackets supporting the pipe, wound the copper around it in tight coils, and scraped both ends clean. He connected one end to the first heavy lead from the junction box and left the second loose until they were ready.

Dulaque and Flynn fought below.

Flynn kept one hand on the sword, but the other returned repeatedly to the wound beneath his coat. Every movement pulled at it, and blood darkened his shirt again. Dulaque drove him backward toward the Stone.

Baird knocked Lamia’s sword away.

The crown flashed.

The blue seam tore open, and Excalibur shot through from the Annex. It turned point downward and drove itself into the Stone of Arthur.

Blue fire filled the crypt.

Magic rushed through the room with enough force to tear Alex from the wall. He caught the pipe with one hand while the loose power lead snapped against the stone beside his head.

Above them, the palace lights exploded.

People screamed on the floors overhead.

The symbols along the crypt walls burned white.

Alex secured the final connection. “Now!”

Ezekiel reached the electrical box.

A Brotherhood soldier grabbed him from behind.

Stone crossed the room, drove one shoulder into the man, and threw him into the wall. Ezekiel flipped the first breaker.

The pipe became magnetic.

Every loose iron weapon in the crypt moved. Swords, knives, and pieces of armor flew upward. Alex flattened himself against the wall as metal struck the pipe around him.

The crown lifted from Lamia’s head.

It stopped halfway to the ceiling, caught between the magnetic field and her control.

Lamia reached for it.

Baird caught her around the waist.

Cassandra dragged one hand through the final line of symbols, breaking the command sequence. “Again!”

Ezekiel threw the second breaker, feeding the coil from the remaining lighting circuit.

The crown tore away from Lamia and struck the iron pipe hard enough to bend the metal band. Excalibur pulled itself from the Stone, flew across the crypt, and struck the crown directly through its center.

The dark metal split in two.

Blue fire erupted outward.

Ezekiel killed the power, and the weapons caught by the magnet clattered back to the floor.

Alex lost his grip.

He fell.

Baird released Lamia and caught him before he struck the ground. The impact drove her to one knee, but she kept him from hitting the stone.

“You’re staying in the Annex next time,” she said.

“There won’t be a next time.”

“Good.”

Lamia lunged toward the broken crown.

Excalibur turned in midair and struck her with the flat of its blade, throwing her across the crypt.

Dulaque watched the magic pouring through the ceiling.

The ritual had succeeded partially. Light traveled along the ancient lines beneath London, spreading beyond the crypt and into the city.

“You’re too late,” he said. “Magic is free.”

Flynn leaned heavily against his sword. “Magic was never gone.”

Dulaque retreated through a side passage while the blue light blinded the room.

The remaining Brotherhood soldiers fled or fell beneath Baird and Stone. Lamia recovered long enough to follow him.

Ezekiel started after her.

Baird stopped him. “Let her go.”

The crypt shook.

Stone looked toward Cassandra. “Can you stop the collapse?”

“The ritual destabilized the foundations.”

“Can you stop it?”

“I’m trying.”

Cassandra pressed both hands to the symbols. Stone joined her, reading the older inscriptions. Ezekiel rerouted power away from the broken ritual lamps.

Alex climbed out of Baird’s grip and crossed toward Flynn.

The wound had opened completely.

Flynn slid down the side of the Stone of Arthur.

Excalibur landed beside him.

A crack from its collision with the crown spread along the blade. Blue light escaped through it, growing fainter with every second.

Cassandra saw him. She left the wall and dropped to her knees beside him.

“The magic in the sword,” Flynn said. “There’s enough left.”

“To heal you,” Baird said.

Flynn shook his head. “To heal her.”

Cassandra stared at him.

“You could cure the tumor,” he continued. “That’s why they chose you. That’s why you did this.”

“I let them into the Library.”

“You made a terrible decision.”

“I betrayed all of you.”

“Yes.”

Cassandra flinched.

Flynn’s voice softened. “You can make another one.”

Alex stood beside the broken crown.

He understood the offer.

Flynn was dying because Cassandra had let Lamia into the Library and given her access to the crown used against him, and he was still giving her the choice no one else had given her. He wasn’t pretending the betrayal hadn’t happened or telling her that desperation excused it.

He was letting her decide what happened next.

Alex had spent years surrounded by adults who called coercion a choice.

He’d almost forgotten what a real one looked like.

Cassandra picked up Excalibur.

The remaining light traveled along her hands.

She looked at Flynn, then toward the symbols still burning across the wall.

“You said I could be a Librarian.”

“You could.”

“If you were choosing again?”

“I’d choose all of you.”

Her gaze moved briefly to Alex.

He shook his head. “Leave me out of it.”

Cassandra laughed through her tears.

Then she pressed Excalibur against Flynn’s wound.

Blue light entered his body.

Flynn arched beneath it. The blood on his shirt vanished. The torn flesh closed beneath Cassandra’s hands.

The crack traveled the full length of Excalibur.

The sword fell still.

Flynn sat up.

Baird touched his face as though confirming he was real.

The remaining blue fire sank into the symbols, and the crypt settled around them.

Cassandra remained kneeling beside the broken sword, one hand pressed against the side of her head. The tumor was still there. The pain hadn’t changed.

Stone approached her slowly.

“I’m sorry,” she said.

He looked at the shattered crown, the dead sword, and the remains of the ritual. “You should be.”

She lowered her eyes.

Stone held out his hand.

After several seconds, Cassandra took it.

They returned to the Annex with the crown broken and Excalibur silent.

The Library was still missing.

For three hours, Jenkins tried the Back Door, seven ancient mirrors, a reflecting pool, and an umbrella stand he refused to explain. Every route led back to the Annex’s supply closet. Whatever fragment of the Library remained could still move objects, alter records, and answer through the lights, but it offered no clue where the rest of it had gone.

Flynn watched from the central table.

“The Library removed itself from time and space,” he said. “Judson and Charlene protected everything inside.”

“Except themselves,” Baird replied.

“They knew what they were doing.”

“That doesn’t make it easier.”

“No.”

Stone placed the broken crown inside a warded case. The Star of Marrakesh rested beside it, waiting to be returned to the Tower once the immediate crisis was over. Ezekiel sat on the edge of the table with three other objects Jenkins had already told him to put back, while Cassandra slept in a chair near the fireplace, exhausted by the ritual and the choices that followed it.

Alex stood near the Back Door.

He’d cleaned the blood from his hands again. Jenkins had found him a dry shirt and a jumper that fit too well to be accidental. The old wound in his chest still ached from being thrown into the wardrobe at the flat and through the display case in the Library, one side of his ribs had begun bruising where Baird caught him, and the cut near his hairline would need something more convincing than “I fell down the stairs” if anyone asked.

Nobody would.

There was no one waiting for him wherever he went next.

Baird joined him.

“You’re not going back to the flat.”

“I’m not.”

“Then where are you going?”

“Somewhere else.”

“That isn’t an answer.”

“It’s the one you’re getting.”

“The Brotherhood found you once. Do you actually have somewhere safe?”

Alex looked at her. “Yes.”

She waited.

Alex had become good at letting silence continue until the other person became uncomfortable. Baird didn’t.

Eventually, he looked at her. “You don’t believe me.”

“I believe you have somewhere else you can get inside. That isn’t necessarily the same thing.”

“I’ll manage.”

“I know.”

The answer irritated him more than doubt would have.

Baird folded her arms. “You shouldn’t have had to.”

Alex looked toward the Back Door. “Does this lead to London?”

“Jenkins says it can.”

“Then I’m leaving.”

“You can.”

He glanced at her.

There was no threat beneath the words. No condition. She hadn’t said he could leave once they debriefed him, once Flynn approved, or once he agreed to return when summoned.

He could leave.

“Flynn wants to talk to you first,” she added.

“That sounds like a condition.”

“It isn’t. You can ignore him.”

“I usually do,” Jenkins said from across the room.

Flynn walked toward them carrying four cream envelopes.

Alex’s was on top. “No.”

“You don’t know what I’m going to say.”

“You’re holding the invitation.”

“The Library reissued them.”

Stone accepted his reluctantly. Ezekiel took his and checked whether there was money inside. Cassandra woke when her envelope settled onto her lap.

Flynn held Alex’s toward him.

“The state of the world has changed. Magic is returning in places where it hasn’t appeared for centuries, and the main Library is gone. There’s too much for one Librarian.”

“That sounds like your problem.”

“It is.”

“Good.”

“The Library chose the four of you because each of you sees things other people miss.”

“I didn’t ask why.”

Flynn lowered the envelope slightly. “You think accepting this means giving the Library the right to decide what happens to you.”

Alex’s expression didn’t change.

Baird looked between them. “Why would he think that?”

Flynn kept his attention on Alex. Something in his expression suggested that the Library had told him more than he intended to repeat.

“That’s his business,” he said. “What matters is that this is an invitation, not an order.”

“They usually start that way,” Alex said.

“Then you have my word that this one ends when you say no.” Flynn held the envelope out again. “You can refuse it, walk through that door, and never hear from us again.”

The Annex lights flickered.

Flynn looked up. “Apparently, it disagrees.”

The flickering stopped.

Jenkins smiled faintly.

“The others?” Alex asked.

“Stone, Cassandra, and Ezekiel will train here as Librarians. Eve will be their Guardian. I’ll search for the main Library.”

“You’re leaving them.”

“I’m giving them room to become something without me telling them what it should be.”

Ezekiel opened his envelope. “Mine says accepted.”

“You didn’t accept it,” Stone said.

“I was thinking about it.”

“The Library reads minds?” Alex asked.

“Only when it’s being rude,” Jenkins said.

Alex picked up his envelope.

The seal opened by itself.

The card inside carried his name, followed by several lines of dark print.

ALEXANDER RIDER

CANDIDATE STATUS: ACTIVE

APPOINTMENT STATUS: DECLINED

FIELD STATUS: UNRESOLVED

Alex read the final line twice.

“What does unresolved mean?”

Jenkins took the card and examined it. “It appears the Library has recognized your refusal while reserving judgment about whether you’ll continue encountering magical incidents.”

“That isn’t its decision.”

“The Library rarely understands boundaries on the first attempt.”

Baird reached for the card. “Can we amend it?”

A fountain pen appeared on the table.

Jenkins picked it up. “Apparently.”

Alex took the pen from him.

A blank section formed beneath his status.

“Can I remove my name from the candidate ledger?”

“No,” Jenkins said.

“Can I prohibit it from tracking me?”

“The Library doesn’t track candidates.”

“It found an unregistered flat in Bermondsey.”

“Perhaps prohibit unsolicited location attempts.”

Alex began writing.

Stone came closer. “What are you doing?”

“Filing a complaint.”

Ezekiel leaned over Alex’s shoulder. “Start with the assassins.”

“I’m starting with the invitation.”

“You’re more bothered by the stationery than the murder cult?”

“The murder cult wasn’t pretending to offer me a choice.”

Cassandra moved beside Stone, still holding her envelope. “You should include age-inappropriate recruitment.”

“International transportation of a minor,” Baird added.

“Unauthorized access to private residences,” Alex said.

“Unsafe working conditions,” Ezekiel suggested.

“You stole a grenade from a display case.”

“It wasn’t labeled.”

“It was labeled in six languages,” Jenkins said.

Flynn drew another chair toward the table. “Failure to disclose the existence of magic before the interview.”

“Failure to disclose that there was an interview,” Alex replied.

“Technically, you never had one.”

“Then improper candidate processing.”

Jenkins brought a second sheet of paper.

Alex looked at it. “How long can the complaint be?”

The Library produced a stack of blank pages.

Baird pulled out the chair beside him.

“It’s learning.”

Alex sat.

The others gathered around the table, offering increasingly unhelpful suggestions while Jenkins explained the Library’s administrative hierarchy and Flynn objected to being named personally in the section concerning reckless conduct in the field.

The Back Door remained ready at the far end of the Annex.

Alex could leave whenever he wanted.

For the moment, he kept writing.
