I have copies of Le Guin's The Dispossessed and The Left Hand of Darkness; I'll likely read those soon. I've so far read three of her books: an essay collection, her YA novel Gifts, and The Lathe of Heaven.
I heard her speak once, at Portland's Wordstock literary festival. By then she'd retired from fiction and was writing more poetry, often political, often hilarious. One poem she shared that time, reading it with a sardonic smile on her face, was called "Loud Cows." She could do that. She also could influence writers all over the place. I've been reading lots of remembrances of her today. Here's Mary Robinette Kowal's.
Ursula Le Guin said, "There have been great societies that did not use the wheel, but there have been no societies that did not tell stories."
