So, technically this book is science fiction, but it is SO INCREDIBLY feminist-friendly I just had to submit it.
All the main protagonists are women, though there are male supporting characters that are fleshed out, too. The three main characters are a spaceship caption, a scientist, and the leader of an alien planet. Two of the main characters are in a relationship.
There’s an alien race that’s able to change their reproductive organs, so either the women OR men can choose to bear children.
Plus, they are empathic – they can sense the emotions of others, which has repercussions on the development of their society.
This is a great feminist book, with an exciting plot! I highly recommend you give it a try!
