In another half century or so, some library will claim the papers of novelist Dario Diofebi toward the close of a distinguished career. Among the earliest documents will be some sort of outline or flow-chart for his debut, “Paradise, Nevada,” and the researcher who finds it will think they’ve stumbled into a three-ring circus.

The term “carnivalesque” could’ve been coined with this novel in mind. Hijinks erupt even from the title, which one character reveals is the name of the township that encompasses most of Las Vegas. Its more common nickname is Sin City, and Diofebi’s hectic spectacular makes room for all its carrying on.
