The Left Hand of Darkness by Ursula K. Le Guin: An emissary arrives on a planet called Winter, where the people are strangely unisexual. That is, they’re asexual until a certain time of the month, when they turn one gender or the other and, er, go into heat, as it were. This is the story of the emissary, who is a human man, as he attempts to convince the people of Winter to join the federation of human worlds. Winter, as its name suggests, is in the middle of a vast ice age. Like many classic SF tales, this is far more about the concept than the plot, but what a concept! The questions it raises regarding gender identity and its effects on society are legion. I wouldn’t say so much that I enjoyed it, but I did find it very interesting. Had the characters been a touch more compelling, it would have been un-put-downable.
