Sixteen-year-old Kara Nightingale’s ordinary life is suddenly turned upside down when she dies and wakes up in a strange new world with a new career—as a rookie for the Guardian Angel Legion. Kara is pulled into the supernatural, where monkeys drive the elevators, oracles scurry above giant crystal balls, and where demons feed on the souls of mortals. br In the Legion, Kara is taught how to use her new abilities and charged with protecting mortal souls from demons. All is about to change when a mysterious mark appears on her leg, and worse, an Elemental child has been kidnapped by demons.
