Tepper crafts a future where men and women live largely apart, raising provocative questions about power, culture, and the consequences of gendered separation.

If you were drawn to how The Disappearance alternated between men’s and women’s experiences after the split, The Left Hand of Darkness offers a similarly rich tapestry of viewpoints.
