Wow! Every bit as brilliant as the first two novels in the series. I don't know what I can say without spoilers, but if you liked the first two, this is a worthy end to the trilogy. We learn even more about all the characters, old and new. The complexities of the Radch Empire make for an exciting story, but the empire is, of course, filled with people, who all have their own agendas.
I cannot say that they author hinted at more books to follow; the ending is clearly the ending. But I was left with a desire to know more about Breq, and the Lieutenants, and even the various ship and station AI's.
I'd give this book five out of five stars
