The Imperial Radch books are a great read as well. They take place in a future in which intelligent space ships are able to control thousands of human bodies connected (enslaved?) to them, experiencing everything these bodies experience at once - the action is great, but it also explores the philosophical implications of this, in a society in which a supreme leader thousands of years old rules over all these ships and all the planets where humans live. There is absolutely no privacy - space stations attached to each colony know everything any of their inhabitants are doing, feeling, even thinking.

This summary doesn't really do it justice - the first book in the series is at https://www.amazon.com/Ancillary-Justice-Imperial-Radch-Leck.... Oh and written by a woman too ;)
