in the world aren't white. Why in the future would we assume they are?" Her 1985 book Always Coming Home, described as "her great experiment", included a story told from the perspective of a young protagonist, but also included poems, rough drawings of plants and animals, myths, and anthropological reports from the matriarchal society of the Kesh, a fictional people living in the Napa valley after a catastrophic global flood. Themes Gender and sexuality Gender and sexuality are prominent themes in a number of Le Guin's works. The Left Hand of Darkness, published in 1969, was among the first books in the genre now known as feminist science fiction, and is the most famous examination of androgyny in science fiction.

Le Guin initially defended her writing; in a 1976 essay "Is Gender Necessary?" she wrote that gender was secondary to the primary theme of loyalty in The Left Hand of Darkness. Le Guin revisited this essay in 1988, and acknowledged that gender
