First the problems: Lacks some of the suspense of previous books and character development is rather rote. The libertarian philosophy (much of which I agree with) is ladled on very heavily, to the detriment of the story’s flow. The story seems to lack a real understanding of how big, both in area and in number of stars, the Tokamak empire (as previously described) actually is. The military strategy is a bit naïve. And the lead antagonist is a rather cartoonish villain, though at least she has actual responses to the clever ideas of the pesky humans.
But the battles are described well, the other non-human races are believable, and we get to the end of a story line.
This series isn’t bad, but if you’re interested in this kind of galaxy-spanning space opera, Weber is a better choice.
