Originally published in 1960, considered by many to now be a sci-fi classic. As it deals with alternate sexuality, Sturgeon’s novel is notable also as a precursor to the feminist sci-fi movement in the early 70s.
“It was my aim in writing Venus Plus X a) to write a decent book b) about sex. It is impossible to attempt such a thing without touching upon religion, which is impossible to do without touching rather heavily upon some of your toes. If this hurts, I am sorry about the pain. My own toes stand firmly upon two planks in the Bill of Rights, and if you have a book which refutes me, I promise that I shall read it with full attention and that I will not burn it.” - postscript by Theodore Sturgeon
