Ember Clarke is on the fast track to becoming the Chicago Supernatural Police Department's best detective. Her biggest strength is her intuition, a power which allows her to sense another's essence and intentions. Her biggest weakness? Trauma from her childhood that's left her with a fear and distrust of vampires. When the girl she's just broken up with is kidnapped and taken to an underground city of the nasty bloodsuckers, Ember knows it was her fault-And she'll do whatever it takes to save her. Even if it means teaming up with a powerful, handsome leech who makes her question everything she knows.
