Balthazar Blake is a master sorcerer in modern-day Manhattan trying to defend the city from his arch-nemesis, Maxim Horvath. Balthazar can’t do it alone, so he recruits Dave Stutler, a seemingly average guy who demonstrates hidden potential, as his reluctant protégé. The sorcerer gives his unwilling accomplice a crash course in the art and science of magic, and together, these unlikely partners work to stop the forces of darkness.

With much of the world’s population now an undead horde, R is a young and oddly introspective zombie. While fighting with and feeding on a human scavenger party, R meets Julie and feels an urge to protect her. What happens next is the beginning of a strangely warm relationship that allows R to begin regaining his humanity. As this change spreads through the local undead population like a virus, Julie and R eventually have to face a larger issue when the very nature of their friendship is challenged. Caught between the paranoid human forces and the ferocious “Bonies”, zombies who are a mutual threat, R and Julie must find a way to bridge the differences of each side to fight for a better world no one thought possible.
