The narrator and protagonist, Red Dorakeen, has vague memories of a place or time that is no longer accessible from the Road. He runs guns to the Greeks at Marathon, trying to recreate history as he remembers it in an attempt to open a new exit from the Road to his half-remembered place. The phrase "Last Exit to Babylon" was the manuscript title of the book and appears on the cover art; it was later used as a title for Volume Four in the "Collected Stories of Roger Zelazny."
