"Ursula K. LeGuin was very good, although I didn't delve into
her fantasy works.. "The Left Hand of Darkness" was as good as they come."

The three original Earthsea books are excellent. They are for children but can be enjoyed by adults, too. I reread them every so often.

I didn't like her later books. I felt the same way about Roger Zelazny. I liked some of his earlier books a lot, especially "Jack of Shadows".

I thought it might have been a somewhat obscure one, so I checked Wikipedia. Appparently it isn't so obscure. The article states:
"Zelazny wrote it in first draft, with no rewrites." On this subject, Truman Capote is quoted as saying "That's not writing, that's typing", (but to Jack Kerouac, not Zelazny).
