Science fiction leading light Ursula K. Le Guin has always gone against the grain. Whether it be filling the pages of her Earthsea children’s fantasy novels with a main cast of Black and Brown characters, or using her dystopian novel The Dispossessed to enumerate the benefits of an anarchist-collectivist society, Le Guin used her incomparable skills as a world-builder to challenge cultural norms.
