Army of Darkness: Furious Road — Nancy A. Collins

Twenty years in the future, the Army of Darkness has succeeded in collapsing Western civilization. An unexpected upshot of the Deadites taking over? Supernatural species such as vampires, witches, and werewolves form an uneasy alliance with humanity in order to survive. The only hope for both mankind and monsters alike is a ritual that will send the demons back to the Hell that birthed them. But first, a rag-tag crew including the Frankenstein Monster and Eva, the Daughter of Dracula, must track down the fabled grimoire known as the Necronomicon Ex-Mortis and deal with its guardian... a certain Ash Williams!
