I finished The Left Hand of Darkness by Ursula K Le Guen.
Genly Ai, a lone human ambassador is sent to the icebound planet of Winter, a world without sexual prejudice where gender is fluid. His goal is to facilitate Winter’s inclusion into a intergalactic federation called Ekumen. Winter is also referred to as Gethen.
Genly faces many challenges though the biggest is his own struggle to understand a society where everyone is gender neutral for most of the time, except for once a month where they become either male or female.
Genly is mistreated and taken to a prison farm, but is rescued by a Gethenian whom he’d previously found it difficult to communicate with. They go on an epic journey and become as friendly as its possible for them to become in the circumstances.
I don’t normally read science fiction, but I will try another of Le Guin’s novels in a few years time when I’ve read all the other books on my reading list.
