Silver Bullet. Preternatural Affairs, #2

Former private investigator Cèsar Hawke has one rule: He doesn't deal with dead bodies. That's why he enlisted with the Magical Violations Department in the Office of Preternatural Affairs. He's happy tracking down witches that commit petty crimes, but he leaves the homicides to other agents. Except that he's been assigned to a new team-a team that handles special investigations-and the job has suddenly changed.
Now Cèsar has to deal with dead bodies. He also has to deal with necromancers, murderous cults, and demons that can stop a man's heart with fear. This isn't the job he signed up for, but it's the job he needs to do. If he can survive the first week.
