The Dispossessed was great! I wanted to read something by Ursula K. Le Guin for ages, and then happened to be staying in a friend's house where that book happened to be on a bookshelf. So I'd the happy experience of just giving it a go, knowing nothing. And it was very good.
Hadn't heard of either of the other two authors though - thank you for sharing!
Le Guin was also anarchist-minded in real life, too. I recall her explicitly endorsing Murray Bookchin in her late years.
The Dispossessed is excellent literature regardless of one's politics, though. The anarchist society depicted in it is utopian, but shown with warts and all fully exposed, and that makes it that much more believable.
I find that it pairs great with Moon is a Harsh Mistress, which, while very different in terms of language and writing (but also great!), sort of does a similar exposition of an anarcho-capitalist utopia - again, warts and all.
