In Radcliffe, perfection is a mask. And Sinclair Arnoult wears his far too well.
Sin is Radcliffe’s golden boy. Star athlete, top student, and heir to a family name that carries weight in every corner of town. With his easy smiles and effortless charm, he’s untouchable.
Perfect.
Petra Valentine has always been an outsider. Trapped in a world of wealth and privilege that barely tolerates her, she’s spent her life fading into the background—until one reckless night at a party changes everything.
A fleeting, drunken mistake ties her to him.
When a series of ritualistic murders forces them together to unravel Radcliffe’s twisted past, Petra discovers that Sin is connected to something far darker than a privileged legacy.
The man everyone worships is hiding dangerous truths—about his past, about the town, and about her.
He swears he’ll protect her. He swears he’d never hurt her.
But in Radcliffe, devotion and destruction look a lot like the same thing.
