Content warning Desolation Called Peace (sequel to Memory Called Empire) minor setting spoilers
Much better than the first part, or to be more precise two parts fit together very well. A lot of open threads and parts of the setting seemed unnecessary, in the second book suddenly came together.
While the first book was for me mainly about immersion in alien culture, second is about things much closer to my heart: finding home, communicating across barriers. There is even some romance.
Also the aliens are very good.
Only minus is this book is still set in facist empire (that is somehow ruled wisely) and the characters are not starting a revolution ;)
