A Perfect Blood

Ritually murdered corpses are appearing across Cincinnati, terrifying amalgams of human and other. Pulled in to help investigate by the Federal Inderland Bureau (FIB), former witch turned day-walking demon Rachel Morgan soon realizes a horrifying truth -- a would-be creator is determined to make his (or her) own demons. But it can't be done without Rachel's blood. As a bounty hunter, Rachel has battled vampires, witches, werewolves, demons, and more -- but humanity itself might be her toughest challenge.
