The Left Hand of Darkness is a 1969 science fiction novel by Ursula K. Le Guin. It is part of the Hainish Cycle, a series of books by Le Guin set in the fictional Hainish universe, which she introduced in 1966. It is among the first books published in the feminist science fiction genre, and the most famous examination of sexless androgyny in science fiction.
Left Hand won both the Hugo and Nebula Awards as the year's "best novel" according to convention participants and science fiction writers respectively. In 1987, Locus: The magazine of the science fiction & fantasy field ranked it number two among "All-Time Best SF Novels", based on a poll of subscribers.[a] That same year, Harold Bloom edited a critical anthology about the book and said in the introduction that "Le Guin, more than Tolkien, has raised fantasy into high literature, for our time".
