Le Guin's work spanned multiple genres and categories but is best known for her work in the science fiction and fantasy realm.
She is particularly well-known for her series of young adult fantasy books that take place in the world of Earthsea, as well as her science-fiction novel 'The Left Hand of Darkness' (Ace Books, 1969), about the meeting of interplanetary cultures.
The book won both the Hugo and the Nebula awards (which are considered the premier awards in that genre), reports CNN.
Her website says she wrote 20 novels, six collections of poetry and many short stories.
