When a 3,000-year-old demon grim reaper discovers someone's killing witches, he'll do whatever it takes to stop them—but everyone knows you can't cheat Death.

3,000-year-old demon grim reaper, Aiden Finn has been in trouble with Management before. Back in 79 A.D., he did some serious time in Hell for disobeying the orders of his boss. He just wants to do his job and stay off of Management's radar, but all that's about to change when he tries to get his latest Charge, Carol, to board the ferry and cross the River Styx after she becomes the latest victim of a serial killer targeting witches.

When Carol refuses to go, Finn promises to find her beloved cat a new home so she'll cooperate. His plan to drop the cat off at a local shelter takes an unexpected turn, however, when he arrives at her apartment and meets Chloe, the stunning red-headed witch who lives across the hall. Hoping to see her again, Finn decides to pet sit the cat instead.

As the number of murdered witches grows, Finn must figure out who is behind the murders before Chloe becomes the next victim. He'll do whatever it takes to stop them, even if it means risking an exorcism by walking into a church and sitting down for tea with a Catholic priest. Of course, if he does find a way to stop the killer—even a grim reaper knows you can't cheat death.
