After Greer Cannon discovers that shoplifting can be a sport and sex can be a superpower, her parents pack her up and send her off to McCracken Hill-a cloistered academy for troubled teens. At McCracken, Greer chafes under the elaborate systems and self-help lingo of therapeutic education. Then Greer meets Addison Bradley. A handsome, charismatic local, Addison seems almost as devoted to Greer as he is to the 12 steps. When he introduces Greer to his mentor Joshua, she finds herself captivated by the older man's calm wisdom. Finally, Greer feels understood.

But Greer starts to question: Where has Joshua come from? What does he want in return for his guidance? The more she digs, the more his lies are exposed. When Joshua's influence over Addison edges them all closer to danger, Greer decides to confront them both. Suddenly, she finds herself on the outside of Joshua's circle. And swiftly, she discovers it's not safe there.
