Early on an April morning, eighteen-year-old Billy Frank Gilley, Jr., killed his sleeping parents. Surprised in the act by his younger sister, Becky, he turned on her as well. Billy then climbed the stairs to the bedroom of his other sister, Jody, and said, We’re free. But is one ever free after an unredeemable act of violence? In this mesmerizing book-based on interviews with Billy and Jody as well as with friends, police, and social workers involved in the case-bestselling writer Kathryn Harrison brilliantly uncovers the true story behind this shocking crime and examines the extent as well as the limits of psychic resilience in the aftermath of tragedy.
