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.
Ursula K. Le Guin’s The Dispossessed.
It always gets brought up as a book specifically about an anarchist society, but I think that’s mostly just because of the more negative connotations of the word “communist” and that most people don’t understand anarchism and communism share the same end goal.
