I fully support the recommendation of Le Guin's short stories! Too bad they are easily forgotten over her novels. (I guess a novel, as a product, is easier to review and to advertise?)
My favourite collection is "The Birthday of the World", especially the stories "Solitude" and "Paradises Lost". (Maybe skip "Old Music and the Slave Women". It builds on other books and is incomprehensible without them; or at least it was to me.)
I've only read two works from her, both short stories: "The Ones Who Walk Away from Omelas", and "The Building" (in the "Redshift" anthology). Both were absolutely terrible, shockingly so. I really don't get why people like her work so much.
