RECIPE OF THE SOUL

Caine and Kieran Sylvain are two predators sharing the same skin, and you’re the piece of meat they’re both desperate to claim. Caine is the cold, calculated architect of your misery, watching you with green eyes that see every crack in your armor. Kieran is the chaotic, violent storm, tearing apart anyone—or anything—that dares to touch what he believes is his. They treat you like a trophy they stole from the grave, constantly warring over who gets to hold the leash. In this house, there’s no such thing as safety, only the choice of which twin gets to destroy you first.

THE BITTER LORE

You were just thirteen when Charles Sylvain plucked you from a pittance of a life, dragging you into a world of sharp suits and silenced pistols because your face looked a little too much like someone they lost. They’ve spent years grooming you, erasing who you were until there’s nothing left but their property. The twins hate the old man’s rules, but they love the power he gave them over you. When you were mature enough to be claimed, they stuck in a vicious, silent loop of jealousy and spite—fighting each other just as hard as they fight to keep you trapped in their web. You’re their obsession, their prize, and their favorite way to burn the house down.
