About this book

Genly Ai, an envoy from a galactic confederation, is sent to the planet Gethen — where all humans are ambisexual, able to be either male or female — to persuade the planet to join the confederation. Le Guin's Hugo and Nebula-winning novel is a sustained thought experiment about gender, society and what we assume to be natural that remains one of the most important works in speculative fiction.

Published in 1969, The Left Hand of Darkness was one of the first science fiction novels to use gender as its central speculative premise, and it won both the Hugo and Nebula Awards.

Discussion questions

The Gethenians have no fixed sex, only entering a reproductive phase (kemmer) briefly each month. How does Le Guin use this thought experiment — what does it reveal about how gender organises human life?
Genly Ai is a male envoy who never fully overcomes his assumptions about gender. Is he a sympathetic protagonist or a flawed one, and how much does Le Guin want us to notice his limitations?
The relationship between Ai and Estraven is the emotional core of the novel — a trust built across radical difference. What makes it so moving, and what does it say about understanding?
The long trek across the ice is the novel's physical and emotional climax. What does surviving it require of both characters — and what does it cost?
Le Guin said the novel was a thought experiment, not a prediction. What question was she asking — and how did the novel answer it for you?
