Le Guin is a fantastic writer. The Lathe of Heaven, The Left Hand of Darkness, and the Eye of the Heron are all excellent and thought provoking novels among Le Guin's other works.
Maybe it was just me not trying hard enough at the time (a decade+ ago); I wanted to read LHoD but couldn't get my hands on it. I know it's now available as an ebook more easily, but I remain a bit peeved about how it was the one thing I couldn't buy legitimately at the time.
That combined with not enjoying Earthsea (I read two or three books?), makes me biased to keep reading any online recommendations but Le Guin.
I didn't like the first Earthsea novel and haven't read any others. I suspect it's a book that tends to work better for young readers, or older readers nostalgic for things they read in their youth.
It's not perfect, but I think where the other books are interesting but simple stories for children, Tehanu feels like it was written for those children as they've grown up - it's basically (without spoiling too much) the retirement and twilight years of characters from the rest of the series. And as a result, it feels like a more applicable or relevant story.
It's currently available in paperback.
On the other hand I was very disappointed from 'A Wizard Of Heartsea'.
