The Genocides

Dystopia by disaster, that is, not caused by man. The characters described are a pretty dislikable bunch, and commit most of the seven deadly sins within this fairly short story.

This novel was nominated for the first year of Nebula awards (1965), losing out to Frank Herbert's Dune. I can't compare those two works (yet), but found this an okay book - Thomas M. Disch's first. Like some of his later horror novels, it is set around Minneapolis (with one of the main characters returning from there shortly before the story begins) - and was a good read for my business trip to that fair city.
