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? He’s distant, intense, and impossible to read… yet Raven feels an instant pull toward him she can’t explain. But Hallow’s Edge is waking up. Students are disappearing. Shadows move where they shouldn’t. And Raven’s dreams are filled with a crying woman and a warning she can’t escape. When Raven’s dormant witch powers begin to stir, she discovers she’s the last heir of a powerful witch bloodline—and Noah is bound to her by a fate older than the town itself.

Nora’s tarot readings were never meant to matter. They were simple moments. A card flip. A quiet truth. Nothing that could ever disturb fate itself. Until the night the cards tremble in her hands. Until the air in the café sharpens and chills. Until something impossible steps out of the shadows. He does not belong to the world around him. His presence presses against it, ancient and heavy, unseen by everyone else. People walk past him without noticing a thing. But Nora sees him. And he is not pleased. He came to investigate the force that dared to bend fate. He expected danger. He expected power. He did not expect the girl sitting at the table with trembling cards. Every instinct tells Nora she should fear him. He is not human. Not mortal. He was never created to feel. Yet something in her pulls at him with a gravity he cannot escape. The more he watches her, the more impossible she becomes. And the more he realizes that whatever awakens inside him will not fade quietly. She may have changed someone’s fate. Now she has his attention. A forbidden attraction. A girl with a gift she barely understands. An immortal who was never meant to want. Until her. Once their paths cross, fate doesn’t just unravel. It begins to fight back.
