Asking for recommendations of fiction books with a communist setting. Ideally with a “show don’t tell” narrative structure. That is, communism exists and works fine but the author does not say “this is communism”. Just existing in the background like any other normal thing.
The first few chapters of Cosmonaut Keep by Ken MacLeod take place in an alternate history where the USSR took over the EU. The author is either an anarchist or a trot and the main antagonist is a "stalinist." The sequel is pretty good, the 3rd book not as much.
The novels Singularity Sky, Iron Sunrise, and Glasshouse by Charles Stross take place in post scarcity settings that aren't explicitly FALGSC but pretty close.
