When Alastair Stone is asked to question a disturbed child who’s committed a horrific act, Stone has no idea what kind of rabbit hole he’s starting down. He uncovers more instances of appalling crimes, all committed by people with no history of violence.
Before long Stone crosses paths with Jason Thayer, a young man searching for his runaway sister who might be a victim of the same bizarre affliction. Stone and Jason are embroiled in a network of odd homeless people, strange symbols, and deadly danger. Even if they find Jason’s sister in time, there’s no way to know if they can help her – and it’s soon clear that the problem’s a lot worse than they originally suspected.
