Who wrote the novel 'The Left Hand of Darkness'?

Ursula K. Le Guin wrote the novel 'The Left Hand of Darkness'.

Published in 1969, the novel is part of Le Guin's Hainish Cycle, a loose future history linking stories about human societies across different worlds. It follows Genly Ai, an envoy of the Ekumen, who travels to the planet Gethen to persuade its nations to join the interplanetary alliance.

Gethen's inhabitants are ambisexual: they have no fixed sex and periodically enter a reproductive state called kemmer. This premise lets Le Guin examine gender, politics, loyalty, and the assumptions outsiders bring to unfamiliar cultures. The book is often associated with feminist science fiction and anthropological science fiction.

The novel won both the Nebula Award and the Hugo Award for Best Novel. Readers sometimes confuse Le Guin with other influential women in science fiction, such as Joanna Russ or Marge Piercy, but neither wrote this novel. Le Guin also wrote the Earthsea books and 'The Dispossessed'.
