Chapter Text
You’d think that after years of living at Camp Half-Blood, I’d have learned to avoid the main bathroom in the middle of the afternoon. You’d be wrong. So was I.
Here’s the thing about being a Hermes cabin kid — a permanent Hermes cabin kid, not one of those weekend warriors who go home to their mortal parent every August — you learn to notice patterns. Where the food goes missing. Who’s cheating at Capture the Flag. Which camper is about to have a bad week. And right now, the pattern I was reading said: Clarisse La Rue is having a bad week, and she’s about to make it someone else’s problem.
That someone else turned out to be the new kid.
I’d seen him already, obviously. Everybody had. Chiron had walked him in that morning looking like a stray dog somebody’d dragged out of a flood — soaked, wide-eyed, half-convinced he was losing his mind. Green eyes. The kind of face that hadn’t figured out yet how to lie to adults. I gave him maybe two days before somebody used him as a punching bag.
Turns out I was right. Just earlier than I expected.
I was cutting through the communal bathroom block near Cabin 11 — the one everybody who isn’t lucky enough to have their own private cabin bathroom actually has to share — on my way to sneak a quick shower before the hot water ran out, when I heard it. Water running wrong. Not shower-wrong. Toilet-wrong. Underneath it, before I even turned the corner, I felt something else — a low, unmistakable thrum against my skin, the water calling out to me, plain as a handshake, coming off whoever was on the other side of that wall. I didn’t know whose kid he was yet. I just knew, instantly and without a shred of doubt, that the sea had noticed him too, and it didn’t much like what was currently being done to him. And under all of that, a voice I’d know blindfolded, underwater, from a mile away, because I’d spent years perfecting the art of not being where that voice was pointed.
“Say it again,” Clarisse was saying. “I didn’t hear you.”
I came around the corner low and quiet — camp reflexes, they don’t turn off just because you’re technically safe — and there he was. New kid. Head in a toilet bowl. Clarisse’s fist a fistful of his hair, holding him there like she was checking if he’d bleach.
And Annabeth Chase was standing three feet away, arms crossed, watching like it was a nature documentary.
I want to be really clear about something, because it matters for basically everything that happens after this: Annabeth’s stillness wasn’t cruelty. It was curiosity. She wanted to see what he’d do. Whether he’d panic, whether something would happen, whether the ocean would notice one of its kids drowning in a toilet. Planning. Studying him. Very typical for her, and I genuinely believe some part of her thought she was doing him a favor.
I did not care about her reasons. I cared that some green, untested new kid — who, if the breakfast rumor mill was right, had lost his mother on the way in and hadn’t even had a full day to catch his breath before Annabeth decided he was worth experimenting on — didn’t even know the rules yet, and had his face in a toilet anyway. Pity got me moving first, honestly. The rest of it — that low, insistent thrum still coming off him even through a wall of tile — was just the thing that kept me from turning back around once I started.
“Hey, Clarisse,” I said. “You’re gonna want to let go of him.”
She didn’t even turn around fully, just enough to sneer at me over her shoulder. “Or what, Lyra? You gonna cry about it? Go steal something.”
Here’s a thing I know about myself, and I’m not proud of it, but I’m not ashamed either: I don’t do fair fights. I’ve never once in my life won a fair fight, because nobody at this camp is dumb enough to give a no-name minor god’s kid a fair fight. So I don’t throw punches. I throw plumbing.
There’s a pipe that runs behind that particular wall, feeding six toilets and four sinks, and I’d mapped it my first month at camp — you keep track of the water in every building you sleep near, because knowing where the pipes are is the difference between getting your teeth kicked in and walking away — and it was old copper, the kind that groans before it breaks. I didn’t even have to touch it. I just asked.
The pipe behind Clarisse’s toilet screamed like a kettle and blew.
Not at Clarisse — I’m reckless, not suicidal, she’d have skinned me — at the floor drain six inches from her boots, so that a geyser of ice-cold water came straight up out of the tile and hit her from the knee down like a fire hose. She yelped, let go of the new kid’s hair on reflex, and staggered back into the wall.
That was all the opening he needed. He came up gasping, and — I remember this really clearly, it’s one of those details that just sticks — the water in the toilet bowl was moving wrong. Swirling against the flush current, curling up toward him like it wanted to check if he was okay.
Nobody else seemed to notice. I noticed. I notice everything about water, it’s sort of my whole deal, and this water was practically screaming at him. I didn’t know who his dad was — everybody was whispering about the Big Three, but honestly, that weird sea-buzz in my ears could’ve meant he belonged to any of the fifty random mud-gods Olympus forgets to invite to parties — but I knew enough to keep my mouth shut about it. Secrets are expensive at camp, and I wasn’t about to give this one away for free. Besides, the kid looked confused enough without me pointing out that the toilet water had been trying to hold his hand.
“You want another round, La Rue?” I said, stepping between them, because apparently I hadn’t learned my lesson from the last six times I’d done this exact thing. “Or you want to go explain to Mr. D why the bathroom’s flooded?”
For about ten whole seconds, standing there in two inches of toilet water, I actually thought I’d won clean. I didn’t know yet that you don’t just borrow the ocean for a favor and walk away owing nothing. Some debts take years to come due.
Clarisse looked at me with the specific hatred she reserves for people who make her look stupid in front of witnesses, glanced at Annabeth like she expected her to help, got none, and stormed out dripping. Which, small mercy, meant I didn’t actually have to fight her, because I would have lost, because I always lose, because camp wasn’t built with a real bed in mind for someone like me — not when the best I’d ever rated was a sleeping bag on somebody else’s floor.
Annabeth lingered a second longer.
“He needed to find out what he could do,” she said, like she was explaining something reasonable to someone unreasonable.
“Yeah, right,” I said. “Try it on your own head next time.”
She left. I did not feel good about making an enemy of Annabeth Chase in my first thirty seconds of meeting the new guy. She remembers everything, steel-trap memory and all. But hey, I’ve traded worse things for a free pass to skip a beating.
That left me and the drowned rat.
He was crouched against the stall wall, coughing, dripping, staring at me like he couldn’t decide if I was a rescue or a second attacker. Smart instinct, actually. Around here it’s usually hard to tell.
“You okay?” I asked.
“I—” He coughed again. “Aside from the toilet water in my hair? Fantastic.” He stared at the drain, still fizzing faintly, then up at me. “Did you just... break the wall with your mind?”
“Old pipes. Camp’s basically held together with duct tape and bad prayers, you just have to know where to push.” I offered him a hand up, mostly because leaving a new kid shivering on a gross tile floor feels like begging the Fates to curse your next meal, and I already get enough mystery meat at dinner anyway. I yanked a spare, faded camp shirt out of the lost-and-found bin by the door on the way and threw it at his chest without much ceremony. “Clarisse does that to everyone. Next time, don’t just stand there and take it. Lyra.”
“Percy.” He took the hand, shirt still clutched in the other. His grip was stronger than I expected from someone who’d just had his head in a toilet. “Thanks. Seriously.”
“Don’t thank me yet. Thank me if Clarisse doesn’t spend the next month trying to get even.”
He hesitated, glancing back at the toilet bowl. “The water was doing something weird, though. Before you even touched the pipe. Like it didn’t want to let me go.”
“Must be bad pipes,” I said, easy, already deciding that was a conversation for another day, if ever. “Camp’s falling apart anyway.”
I studied him a second — waterlogged sneakers, a scrape on his elbow, that stunned, still-catching-up look every new demigod wears for about a week before camp either turns them into fighters or uses them for target practice. “You’re the one everybody’s whispering about. The Big Three rumor.”
“I don’t even know what that means.”
“You will.” I turned to go, because I had somewhere to be and a shower I still hadn’t stolen, and because sticking around to make friends with the new kid wasn’t part of the plan. I don’t do friends. Friends are just people who are going to get themselves killed and leave you with their chores.
“Wait,” he said. “Why’d you help me? You don’t even know me.”
Good question. I still don’t have a great answer, even looking back on it now, except that I know exactly what it looks like when somebody decides you’re the easiest target in the room, and I’ve been the punching bag more times than I’ll ever tell anyone. Including him. Especially him. That, and the sea had practically slammed into my chest the second I walked around that corner — some old, stubborn instinct in me has never once been able to walk past one of my own and just keep going, whether or not I say so out loud.
“Free bathroom show,” I said instead. “Don’t get used to it.”
I didn’t stick around to see his face. I had places to be — a shower to sneak, a life to keep running the way I’d built it, one careful theft and one careful lie at a time.
I didn’t think about the drowned rat in the bathroom again for the rest of the day. That was a mistake. I make a lot of those. I forgot that once the ocean takes an interest in you, it doesn’t just let you walk away.
I’d find that out soon enough.
Nobody explained camp to Percy Jackson. That was the first thing I noticed, and it bugged me way more than it should have.
I want to be clear that this isn’t normal camp policy. New kids get a tour. Somebody’s supposed to walk them through the cabins, point out the volleyball pit, tell them which nymphs bite and which ones just flirt, explain that the harpies eat you if you’re out after curfew and mean it literally, not as some joke or a fancy word for getting detention. It’s not written down anywhere, but it’s tradition, same as the campfire songs and the bad chariot puns.
Except the morning after the bathroom incident, I watched Percy wander out of Cabin 11 at breakfast looking like a lost dog who’d wandered onto the wrong farm, and not one single person went over to help him. Half the camp had already decided he was Big Three material based purely on rumor — nobody knew whose kid he was yet, but “unclaimed and Clarisse hates him already” is basically a golden ticket for speculation around here — and the other half had decided, correctly, that getting anywhere near Clarisse’s new grudge was asking for a spear in the back.
Annabeth wasn’t helping him either. I clocked her watching him from the Athena table, blueprint-brain practically visible behind her eyes, cataloguing. She does that. Files people like they’re weapons she’s keeping track of until she decides if they’re actually useful. I’ve never liked that about her — the way she treats people like puzzles instead of people — though to be fair I’ve never given her much of a chance to prove me wrong, because I go out of my way not to be around her long enough to find out. Smartest kid in camp, technically. But I’m not interested in being one of her science experiments.
So that left the job to me. Nobody assigned it. I just looked at Percy standing there holding a tray he didn’t know where to put, and thought: fine. Guess it’s me, then.
“You’re doing it wrong,” I said, sliding onto the bench across from him before he could sit somewhere that would get him laughed at. “You don’t just sit anywhere. Table’s assigned by cabin — you’re Cabin 11 for now, unclaimed, so you sit at the end. Not the middle. The middle’s for people who’ve been claimed less than a week, it’s like a trial period for new people, don’t ask me who made that rule.”
Percy looked down at his tray, then back up at the pavilion like he was only now noticing it ran on rules nobody had bothered writing down anywhere for him. “There’s an actual seating chart. For an unclaimed-kids cabin. That’s — okay. Sure. Why not.”
“Camp’s got a rule for everything,” I said. “Nobody explains most of them until you’ve already broken one.”
He blinked at me, something shifting behind his eyes like he’d only just placed where he recognized me from. “You’re the toilet girl.”
“I’m the girl who saved you from a toilet. Different thing. Lyra, daughter of Glaucus, in case you forgot in the last twelve hours.”
“Glaucus?”
“Exactly the reaction I get every time,” I said, and mentally kicked myself. Note to self: keep your mouth shut. “Since apparently nobody’s told you this yet — you don’t say any god’s name out loud. Not the big ones, not the small ones, not ever, not if you can help it. Camp’s about as safe as it gets for that particular rule, and even here it’s more ‘mostly fine’ than ‘actually fine.’ Your own godly parent’s usually the only one you can get away with saying, since a god’s generally not going to smite their own kid for saying dad’s name over breakfast — but ‘usually’ isn’t ‘always,’ and he hasn’t exactly dropped a sign to tell me if he’s cool with it, so I don’t push my luck. The god of sailors,” I went on, deliberately, “old, minor, currently hasn’t claimed me, which around here means officially I don’t exist as far as he’s concerned. My mom told me who he was before she died, so I’ve always known. Not that Chiron or the counselors give a damn. Out here, if your dad doesn’t have a golden throne on Olympus, you don’t get a roof. You get the floor of Cabin Eleven. Even if he flashed a glowing neon sign over my head right now, it wouldn’t change a thing. There is no Cabin Thirteen. So as far as the camp roster goes, I’m just another ‘unclaimed’ kid stuck sleeping on a gym mat like a stray dog. But honestly? Best deal in camp. No godly visits, no prophecies, nobody watching over my shoulder. I get left alone.” I nodded at his tray. “Also, scrape a little food into the fire pit before you eat. It’s an offering thing. You skip it, the gods notice, and trust me, you do not want extra godly attention right now. Or ever, honestly.”
“Why not?”
“Because gods are basically nukes with personalities,” I said. “You don’t want a nuke noticing you exist. You want a nuke to forget your name.”
That got the first almost-smile I’d seen out of him. Small thing. I brushed it off, ignoring the weird little spark of pride in my chest.
Here’s the thing about Cabin 11. Everybody who tells you Hermes is the “unclaimed kids and thieves” cabin makes it sound like a punishment. It’s not. It’s the most crowded room at camp, bunks stacked three high, gear piled in every corner because nobody has their own shelf, and it runs almost entirely on swaps and favors, because that’s what happens when you cram forty kids with nothing into one space — you either learn to trade, or you go hungry.
I’d been dealing in that stuff for years. I knew who had spare socks and who’d trade them for cafeteria dessert, who could pick a lock and who’d teach you for the price of a favor owed later, which counselor turned a blind eye to curfew if you brought them coffee from the Big House. It’s not glamorous. It’s just how you survive a place that mostly forgets you exist until you’re useful, or until your godly parent finally remembers you’re alive.
Percy didn’t know any of it. So I told him. Where the showers actually had hot water after 8 p.m. (the ones behind the armory, everyone else fights over the main ones). Which camper to avoid asking for anything (Travis and Connor Stoll would trade you a “favor” that always somehow ended up costing you double). Where the food actually got good on Fridays — pizza night, and if you didn’t grab a slice in the first five minutes it was gone, because the Ares table didn’t believe in leaving anything behind for the rest of us. Who to stay three tables away from at all times — which, this particular week, was a short list with Clarisse’s name circled twice.
“Clarisse,” he guessed.
“Clarisse,” I agreed. “But also — Annabeth.”
He frowned. “She seemed fine? Kind of a know-it-all, but—”
“She’s not dangerous like Clarisse is dangerous,” I said, which was true, and also not the whole reason, and I wasn’t in the mood to go into all that with a kid I’d known for one day. “She’s just — look, she’ll want to run your whole life like a military drill if you let her. Some people like that. I don’t. Your call.”
I did not tell him the rest of it. That I’d overheard her, once, describing an unclaimed kid’s odds of surviving their first monster attack out loud, casually, like she was reading poker odds, and something in me had gone cold and permanent about her ever since. That’s not a story I hand out for free. Not on day one. Maybe not ever.
Sword training was that afternoon, and it was, hands down, the funniest thing I’d seen at camp in years, which is saying something, because I once watched a satyr try to flirt with a dryad by reciting his own poetry and it went about as well as you’d expect.
Luke Castellan ran the arena that summer. Golden boy, scar down one side of his face that made him look like he’d survived something instead of what actually happened — long story, not mine to tell — and a smile that every camper under fourteen was a little in love with. Everybody thought Luke was the best thing that had ever happened to Camp Half-Blood.
I thought Luke Castellan treated unclaimed nobodies like furniture, and I had exactly zero interest in playing along just to make him feel good. I stood at the back of the group during his demonstrations. I answered when spoken to and not one syllable more. If he noticed the difference between how he was treated by me and how he was treated by literally everyone else at camp, he never said anything about it. Probably didn’t think I was worth the effort of asking.
Percy, on his first day with a sword in his hand, was — to be nice about it — a disaster. He held the practice blade like it might bite him. His footwork looked like he was trying to dance on roller skates for the first time. Luke paired him against another camper for a basic drill and Percy managed to trip over his own feet twice before anyone even swung at him.
“He’s hopeless,” muttered Mason, an Ares camper who’d clearly inherited every last drop of his cabin’s short fuse and none of its actual fighting skill. We got paired up for drills more often than anyone else bothered to track, mostly because nobody else wanted to spar against someone they couldn’t intimidate into quitting early. Not friends. He’d never once asked me a personal question in three years of swinging blades at each other. But he showed up to every single session I did, and somewhere around year two he’d stopped sneering at that and started just expecting it, which from an Ares kid is about as close to respect as you get without an actual compliment attached.
“He’s new,” I said. “Give him a week.”
I don’t know why I defended him. I do know that I spent the rest of the session watching him more than I watched my own footwork, which got me yelled at by one of the older Ares kids for sloppy form, which was fair, honestly, because I wasn’t paying attention to my own blade at all.
Afterward, while everyone else filed out toward the showers, Percy sat on a bench looking at the sword in his hands like it had personally betrayed him.
“I’m never going to be good at this,” he said.
“No,” I agreed. “Not with that sword, anyway. It’s too heavy for you — you’re jerking your shoulder on every swing because you’re fighting the weight instead of the blade. You need something balanced for speed, not power.”
“How do you know that?”
“Because I’ve spent years watching a hundred different kids fail at exactly the same thing before somebody finally told them,” I said. “Nobody told you. So. I’m telling you.”
He looked at me for a second too long, like he was trying to work out why I kept popping up out of nowhere. I didn’t have a great answer for him. I still don’t, if I’m honest — except that I knew what it looked like to be dropped into this place with absolutely nobody in your corner, and some stubborn, stupid part of my brain had apparently decided he wasn’t going to find that out the hard way. Not while I was standing right there.
“Come on,” I said, standing up before things could get all sappy. “I’ll show you where the good showers are before the Ares cabin claims them all.”
He followed me. That was sort of how it started — not with a quest, not with a claim from any god, just a kid who didn’t know the rules yet, and a girl who’d decided, without really asking herself why, that she was going to make sure somebody explained them to him.
Neither of us knew yet how much trouble that one choice was going to drag us into. But that’s the thing about the ocean — by the time you realize you’re caught in the undertow, it’s already too late to swim back.
