The time [of Deus Irae, written by Zelazny and Philip K. Dick] is post-World War III; the place a wasteland America, peopled with mutant races and presided over by a God of Wrath, one Carleton Lufteufel, who had been instrumental in bringing about World War III in the first place. Tibor McMasters, an incomplete (born without arms or legs, fitted with bionic counterparts), is commissioned to seek out the God of Wrath and to paint his portrait. It is the search for Lufteufel, and its implications, which the book explores. Dick and Zelazny's names will draw hard-core science fiction freaks—the only ones who will stay with this philosophical, allusive tale.
