Aliette de Bodard's'House of Shattered Wings' might fit your bill although it has the same issue as 'The Fifth Season' in that it definitely feels like the first part of a longer story.

And by cis white dude but a really good SF with spaceships story that engages with SFnal ideas in ways that I hadn't thought about -- AURORA by Kim Stanley Robinson. caveat that I've never read him before so I don't know how much it is the same as his other books but I was impressed.
