Born into a family of Guardians—extraordinarily gifted humans who protect mortal souls—seventeen-year-old Rose Kazin shows no signs of being blessed with the supernatural talents her family has used for generations to fight demons. When she and her father figure, an age old celestial Warrior, are horribly wounded in a demonic ambush, Rose awakens to find a younger Warrior, Ouriel, has volunteered to stand in as her protector. She rails against his presence—and her own heart—but Ouriel seems interested in only one thing: teaching Rose how to protect herself from the demons she was never supposed to fight.
