A pretty good sci-fi book by Ann Leckie. Read in the late Summer of 2022.
2014 Hugo & Nebula award winner. So...it should be good.
An interesting idea that is explored through the book: AI's reside in ships, and take over multiple human bodies to act as their living embodiments. They exist simultaneously in all the bodies and are connected via...tech?
I did not keep track of all the characters - there were many and their names were difficult to remember.
Although it wasn't mentioned specifically, I think all the characters were women.
