This is a quite good combat science fiction book. I'm not really sure how I discovered this series, but I'm glad I did. There are some new ideas here, as well as some that mirror John Ring (incompetence in command) and Keith Laumer (alien invasion). Overall and enjoyable read, and I'll be reading more from this series.
This is the third book in the Robot City series, which is based in Asimov's Foundation universe. This one follows Odyssey and Suspicion, and is a pretty good book. Its also a very fast read. The robot-wandering-the-city subplot is very reminiscent of Caliban, which is yet another Asimov spinoff. The plot lines are different enough that it doesn't feel like a rehash, but there are certainly strikingly similar elements. I liked this book.
