After breaking a quantum-interference device, mild-mannered comic book store owner Stuart Bloom must save the universe from imminent destruction.

Stuart, Bert, Denise, and Barry Kripke find themselves in what appears to be an ideal and peaceful Earth - that happens to be controlled by a repressive and vicious AI.

In a world where magic is real, Bert discovers a gift for sorcery, while Stuart enlists the help of one of this universe's most powerful wizards.
