Now that I have finished the second of Ann Leckie's Imperial Radch series (Ancillary Sword), I am ready to start the third. This series is more what I would call social SciFi. The protagonist of the series must navigate, not only his ship, but all the social, cultural and gender norms of the different peoples he engages with. The gender references can be a bit confusing, so if you start the series, pay particular attention to the description of how the different cultures refer to themselves. Mostly, though, it seems regardless whether you are a he or she, they seem to refer to everyone as a she. The business of wearing gloves in public was a little odd, but the why of that got explained in book two. I already downloaded book three, but will start that after I finish up the first of Greg Alanson's offshoot of his popular Expeditionary Force series, Mavericks: Deathtrap which follows the part of the force that was left behind at a planet they call Paradise.
BTW, while the Expeditionary Force series is fun and has an number of memorable characters, I think Ann Leckie's series give you more to think about regarding cultural norms, not only in the books, but in real life too. It also reminds you that direct translations of different language can sometimes get you because of differing cultural understanding of the word in question. Some words while the direct translation may be "correct" in literal terms, the word may be an insult in another culture.
I haven't listened to my audio book the last few days--must get back to that, too.
