The Left Hand of Darkness Author:Ursula K. LeGuin Not since DUNE has a science fiction novel generated as much enthusiasm and excitement as THE LEFT HAND OF DARKNESS. Discover for yourself this thought-provoking take of an alien planet where all the people are of the same sex, and the lone earthman is forced into a subtle planetary intrigue where he is the pawn and his future is the prize.
A good SF story with a few weaknesses. LeGuin hammers on the point that "sex colors everything" a bit too much. I don't buy it. But that and a couple of nits aside, this is a classic tale. Don't expect space opera, though. This is about relationships and politics, not space battles.
