Discworld's only demonology hacker, Eric, is about to make life very difficult for the rest of Ankh-Morpork's denizens. This would-be Faust is very bad--at his work, that is. Eric wants to fulfill three wishes: to live forever, to be master of the universe, and to have a hot babe. Instead of conjuring a demon, Eric brings forth a wizard whose incompetence is matched only by Eric's.
