Raised in a family of demon hunters, Blair Murphy has her own personal demons to fight - the father who trained then abandoned her, and the fiance who walked out on her after learning what she is. Now she finds herself training a sorcerer from 12th century Ireland, a witch from modern day New York, a scholar, and a shape-shifter from the mythical land of Geall, while trying to keep herself from staking the sixth of their circle: a vampire sired by Lilith, the vampire queen the've been charged with defeating. No stranger to a good fight, Blair finds she has met her match when it comes to that handsome and flirtatious shape-shifter Larkin. And a couple of run-ins with one of Lilith's loyal followers gives Blair more than she reckoned for, mentally and physically. But will she be able to stay alive long enough to defeat Lilith's army? Or will she find herself falling for the one thing she vowed never to give into again?
