Ancillary Justice

This is a fun space opera that has all the fun space opera things: giant interstellar empires; worldbuilding on various interstellar cultures, and how they interact with each other, and how they do gender; exploration of how cognition and identity works in entities that are not (or not entirely) human; grand plots and conspiracies.

The overall plot is perhaps a bit simple, and some of the characters lean perhaps too much into one-dimensional archetypes, but it does not matter that much against the lively worldbuilding, and how it ties into the whole story.
