Basically a post apocalyptic novel of a society living in a multi-level underground silo. The upper echelon tech and IT residence live closer to the surface. The lower echelon blue collars live and work near the bottom. Law breakers are selected to enter the still poisonous surface to clean up and wipe off the surveillance camera lens with a wool cloth.
Lots of intrigue and parallels to todays societal breakdowns.
Freaky. Especially in todays happenings.
