School bullies, home neglect, and loneliness fill 13-year-old Angelina's (or Angel, as she's known) life, but she's busy planning payback on her tormentors and secretly observing her apartment neighbors at night. Her one and only friend, Colt, is an intriguing boy who only appears during the darkness of night or when the lights fade away. As outcasts, they share a powerful connection. But when Colt's guardian vanishes during a string of horrifying murders, Angel can't help but wonder if he's hiding a dark and dangerous secret.
