"A contemporary Buffy."—Publishers Weekly "Readers will devour this fantastic series starter. ...Barnes brings her characters to life in stunning detail. This is not your usual paranormal fare."—RTBook Reviews Every other day, Kali D'Angelo is a normal sixteen-year-old girl. She goes to public high school. She attends pep rallies (reluctantly). She's human. And every other day in between . . . she's not. Though she's not quite sure what she is on those days, Kali knows what she does . . . she hunts, traps, and kills demons, hellhounds, and other supernatural creatures that threaten her world. On those days, she is practically indestructible. But when Kali notices a mark on a popular girl at school, she knows instantly that the girl is marked for death by one of these unworldly beings. And she knows she has only twenty-four hours to save her. There's only one problem . . . it's the wrong twenty-four hours.
