Seventeen‑year‑old Raven has spent her whole life drifting through the foster system, never staying long enough to call anywhere home. With her eighteenth birthday—and the end of state support—only weeks away, she’s sent to the strange little town of Hallow’s Edge, a place obsessed with Halloween and thick with secrets. The Connors, her new foster family, are nothing like the others. Warm. Protective. Magical. And their son Noah?

Kael Ashford was raised to inherit an empire built on blood — and to want nothing else. Love, to him, isn’t weakness. It’s a liability he was trained out of before he could walk.

Because Rowan isn’t as innocent as he looks, and the longer Kael keeps him alive to find out why, the more he starts to wonder which of them is really the one being unraveled. Some secrets are worth dying for. Kael is about to learn that some are worth killing for, too — and that the boy in his mansion might be the only person left who can do either to him.
