The Left Hand of Darkness

Read this as part of a college class with Bloodchild by Octavia Butler. Both of these stories are quite remarkable. This one in particular really challenges and makes you consider real world society in comparison to what we see in the story.

I long expected one of the Earthsea books to be my first Le Guin read (they've been on my want to read list for a long time), but I am glad this one was it in the end.
