Kael has stolen many things—but never something that could steal him back. After a botched heist in a hidden church of killers and sinners, he escapes with nothing but an old, useless book. Or so he thought. The book whispers. It watches. And when Kael answers its call, a presence enters his life—one that promises he will not die… but never says he will remain the same. As ancient words reveal a forbidden name, Kael realizes too late: He didn’t find the book. The book found him.
