Genderweird Worldbuilding in SFF

This is NOT for books featuring trans or nonbinary protagonists in worlds with gender systems that mimic modern real-world ones. This is for books like Left Hand of Darkness or the Imperial Radch series, where the setting has an invented system of gender and/or sex, or of assigning gender/sex. I'm including interesting-to-me matriarchies (so, not ones that are just our patriarchy but gender-swapped) and gender systems that include male and female but have other genders/sexes too.

Suggestions are extremely welcome!

There's a book called Shadow Man by Melissa Scott. Had explanations for the sexes/genders and their pronouns and pronunciations (A don't remember which or how many of each existed, which is the only reason I am equating these here). A bit to political plot focused for me, but I believe this may align with what you're looking for. But it's been a while.

Excellent suggestion! I read that recently but completely forgot I could add it to this list, so thank you!

I would recommend the murderbot diaries series for this list, there's robots with neutral/no gender and humans basically self-identify as anything with specific planets/stations/etc having their own "neo-genders". The books don't really explain it but it's still really interesting.

Good suggestion, thanks!

Reccing Becky Chambers Wayfarers series, especially first and second books. Contains a hive mind, multiple genderfluid/sexfluid aliens, and AI discovering their own form of gender, as well as several others I can’t fully remember currently 🥰

I'm not sure those count in the way I meant for this list - I've read and adored the series, but it's a lot of individual characters with unconventional genders, we don't see the worldbuilding around gender, imo? Possibly I'm forgetting something...?

There’s more of focus on one of the alien species expression of gender/sex in the second book from what I remember, there’s a festival linked to the shifts in gender and it’s shown more there in the world building than in the first? But entirely fair if it’s not quite what you’re looking for 😊

I should reread them and see :D Thank you for the suggestion either way, I appreciate it!
