On the surface, Annie’s life in a wealthy Florida suburb is happy. Her husband, Gray, loves her fiercely; together, they dote on their beautiful young daughter, Victory. But the bubble surrounding Annie is pricked when the demons of her past resurface. These are demons she can’t fully recall because of a highly dissociative state that allowed her to forget the violence of her earlier life as Ophelia March and to start over, under Gray's protection, as Annie Powers. Disturbing events—the appearance of a familiar dark figure on the beach, the mysterious murder of her psychologist—trigger confusing memories for Annie, who realizes she must quickly piece them together before her past comes to claim her future and her daughter.
