Summary
Olivia was Strange. She always has been strange, especially according to her mother. Olivia was Born Strange, and really, she was perfectly Okay with that. Olivia was strange, she was born with blank sapphire bright blue eyes and smooth black hair with only a hint of curl to it and a word written in clear elegant script on her copper toned little forearm. The writing was clear, and yet somehow it Gave off a feeling of Warning whenever you looked at it for more than a moment. It read

Summary
In this AU, when Luke turns up at Valentine’s doorstep after his first, agonising transformation into a werewolf, he doesn’t get dragged away into the woods. Instead, Valentine captures and imprisons him in chains, in the cold stony dungeon that he made with the intention of experimenting on Downworlders.
Valentine’s plan is clinical, almost elegant in its cruelty: here was a rare find, a newly turned, healthy werewolf who had once been Nephilim. The perfect subject for his research into demon blood’s effects on Downworlders, especially one with a Shadowhunter’s strength still woven into his bones.
But the plan takes a dangerous turn. After the first injection of demon blood, Luke’s body reacts in a way Valentine didn’t anticipate—plunging him into a sudden, raw, and consuming heat. And Valentine, already corrupted and unmoored by his own exposure to the same poison, finds himself standing at the edge of an entirely different kind of experiment… one that could unravel both of them in ways far beyond what he intended.

Summary
Neil Josten was running. Somewhere on the California coast he and his mother had been attacked by a monster he couldn’t name, and there he’d left her body.
He’d known since he was a kid there was something different about him, the things he could see. But maybe he was not nearly as unique as he thought. When he’s brought into the world of Shadowhunters and downworlders Neil realized the world he’d been seeing had existed beneath the noses of everybody else all along.

Summary
"I’ve been possessed, Reggie has been possessed, Julie was brought back to life and possessed and the Clave didn’t think to stop by. Lilith was walking around and they were just calling us in to talk," Luke said.
“They wouldn’t show up just because we have more demons than usual…” Flynn trailed off.
“Exactly,” he said, gesturing at her.
“We’re not-” Julie sighed, a hand going through her hair as she paced around the room. She’d barely woken up and already her whole day was going off the rails. Considering how her life had been lately it wasn’t exactly shocking. But still… “We’re not asking the right question.”
“What do you mean?” Flynn asked.
“If there is a warlock involved here they summoned Asmodeus, they’ve been summoning demons because they know they’ll come for me,” she said, turning to look at them. “They know. And the only other person who knows is Caleb. What we should be asking here is-”
“-how is Caleb talking to the outside world,” Flynn finished for her.
“Yes,” she said. “Because the Clave suddenly taking residence here at the same time Caleb decided to blackmail us is way too big of a coincidence.”

Summary
Seven souls marked by old magic, hiding in plain sight, sworn to stay together as a pack. But the balance is breaking.
One vanishes after a demon hunt goes wrong, leaving behind only blood... and questions.
Another wakes to find a sigil seared into his skin, with no memory of how it got there.
A third catches glimpses of wings—shadowed, vast—in mirrors and glass, as if something inside him is learning to fly.
One is hunted by both angels and demons, a hybrid neither realm will claim.
Another’s wolf instincts are rising, clawing at the edges of his mind, harder to control each time the moon shifts.
Someone has begun meeting with the Faerie Courts, risking the fragile neutrality they’ve all fought to protect.
And two of them can feel it: the vows of the Runeborne Pact are weakening, and something ancient is stirring beneath the surface.They love each other. Fiercely. Quietly. Desperately.
But no one dares speak it—not when silence is safer than breaking what little peace they have left.
No love triangles. No easy choices. Just a quiet storm of longing tangled between them all.They must choose: remain hidden in the shadows… or rise, and burn the world down.

Chigiri glared at him. “You of all people talk about putting feelings aside. Of course. Fuck me, I’m done here.”Shadowhunters Kunigami Rensuke and Chigiri Hyouma are forced to work together.

Summary
A cursed relic. A drop of silver-blue blood. A legend that should have died long ago.
James Potter and his parabatai, Sirius Black, follow the trail into the shadows of London, where the weight of old secrets and forbidden power stirs. Whispers speak of the Crown of Thorns, a lost artifact that could shatter the balance between Shadowhunters and Downworlders. The Clave wants it. Others would kill for it. And James? He’s beginning to fear his own bloodline holds the key.
When Regulus Black returns to the Institute and a stranger—who should never have seen them—crosses their path, the lines between past and present, loyalty and betrayal, begin to blur. Some relics should remain lost. Some truths should never be uncovered.
But the hunt has already begun. And something in the dark is watching.
