The devil you know - Jenna Black

The beautiful. The bad. The possessed.

Some people worship them. Some people fear them. And some people-like Morgan Kingsley-go up against them toe-to-toe, flesh to flesh, and power against power. An exorcist by trade, Morgan is one of the few humans with an aura stronger than her possessor, even though her demon can tease her body senseless. She's also a woman who has just discovered a shocking truth: everything she once believed about her past, her identity, may have been a lie.

With a family secret exploding around her and a full-scale demon war igniting, Morgan is a key player in an unsettled world. Then a rogue sociopathic demon enters her life with a bang. His name is The Hunter. And since she is the prey, Morgan has only one choice: to hunt The Hunter down-no matter what heartbreaking truths she uncovers along the way..
