The New York Times bestselling author returns with the latest installment in the sexy, supernatural adventures of Rachel Morgan—"one of urban fantasy's most charming witches" (Publishers Weekly).

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.
