The orphaned daughter of a sorcerer and a half-demon, Savannah is a terrifyingly powerful young witch who has never been able to resist the chance to throw her magical weight around. But at twenty-one she knows she needs to grow up and prove to her guardians, Paige and Lucas, that she can be a responsible member of their supernatural detective agency. So she jumps at the chance to fly solo, investigating the mysterious deaths of three young women in a nearby factory town, as a favour to one of the agency's associates. At first glance, the murders look garden-variety human, but on closer inspection signs point to otherworldly stakes.
