The underground population of witches, vampires, werewolves—creatures of dreams and nightmares—has lived beside humans for centuries, hiding their powers. But afterwards a genetically engineered virus wipes out a large part of humanity, many of the "Inderlanders" reveal themselves, varying everything.
Rachel Morgan, witch and bounty hunter together with the Inderland Runner Services, is one of the excellent at apprehending supernatural lawbreakers throughout Cincinnati, but when it comes to following the rules, she falls desperately short. Determined to buck the system, she quits and takes off on the run together with an I.S. contract on her head and is reluctantly forced to team up together with Ivy, Inderland's excellent runner . . . and a living vampire. But this witch is way out of her league, and to clear her name, Rachel must evade form-varying assassins, outwit a great businessman/crime lord, and survive a vicious underground fight-to-the-death . . . not to mention her own roommate.
