@Maenad it's not hard sci fi, it's superhero stories, but I'd highly recommend Dreadnought and Sovreign by April Daniels. it was a good story, made me feel a lot of feelings.

and while she's cis, there's also our very own @guerrillarain, who writes extremely gay sci fi and fantasy serials. she's so talented, and you'd be doing yourself a disservice by not reading her work.
