Sacrificial Magic (The Chess Putnam Series‪)‬

Reading, writing, and raising the dead
 
When Chess Putnam is ordered by an infamous crime boss—who also happens to be her drug dealer—to use her powers as a witch to solve a grisly murder involving dark magic, she knows she must rise to the challenge. Adding to the intensity, her boyfriend, Terrible, doesn’t trust her, and Lex, the son of a rival crime lord, is trying to reignite the old sparks between them.

Plus, there’s the little matter of Chess’ real job as a ghost hunter for the Church of Real Truth. She’s investigating reports of a haunting at a school in the heart of Downside, where someone seems to be taking a crash course in summoning the dead—and if Chess doesn’t watch her back, she may soon be joining their ranks. 

As Chess is drawn into a shadowy world of twisted secrets and dark violence, it soon becomes clear that she’s not going to emerge from its depths without making the ultimate sacrifice.
