Finishing the Imperial Radch sci-fi trilogy (Ancillary Justice/Sword/Mercy) by Ann Leckie. Despite the agender language feature (everyone is addressed as she) the books deal more with colonialism, imperialism, and personal identity, rather than gender. Writing style is very information-dense, lots of thoughts and actions happening simultaneously. Compared to other science fiction that I read, it gets much more into the cultural and interpersonal situations, especially the second book.
