Underworld is not a linear narrative, and deals with many intertwined themes. A central character is that of Nick Shay, a waste management executive, who leads a undirected existence in late 20th century America. His wife, Marion, is having an affair with one of his friends.
Waste is an extended metaphor throughout the novel. It explores themes of fractured identity and the ways in which construct meaning in contemporary American life. A central extended metaphor is that of religion and the underworld of nuclear technology and its power structures.Synopsis
