On a sunny morning in June, Margaret Carpenter wakes up to find a new iPhone on her doorstep. She switches it and is greeted by a text from her best friend, Charity Atwater. The problem is, Charity’s been missing for over a month. Most people in town—even the police—think she’s dead.

Margaret and Charity have been lifelong friends. They share everything, know the most intimate details about each another…except for the destructive secret hidden from them both.
