As a person actively organizing with anarchists and who has had a lot of long, fraught relationships leading to my late 40s, I found the Dispossessed to be relatable is ways I wouldn't have if I'd read it earlier in life.
I don't know if it's a difficult book, but I can see how it might land differently for me in different situations.
