It's a wonderful and very insightful review. My favorite bit:
...this is not a space opera with a ton of action scenes in it. This is a novel far more interested in the political machinations, maneuvers, conversations, revelations and negotiations than in straight up conflicts. If you prefer your space opera with more laser guns and less wrangling, this is not quite the space opera you are looking for. On the other hand, if you want deadly dances of interstellar politics, this novel, this universe, has all you could want, in spades, and will eat up what is offered here with as poon.
