Excellent!
This was a thoroughly enjoyable story. It is well written, there are few distracting typos and grammar issues, and the story is well conceived and planned. The characters are well developed and behave consistently.
On the surface, a future world colonized by humans after Earth is destroyed is a relatively orthodox sci-fi formula. But the addition of the laws against high tech in the interest of keeping humans from destroying their new world, too, raises this story to another level. The fact that contraband tech crops up seems inevitable to me under these circumstances. The handling of it is plausible, although I do rather wonder about the military not researching tech during wartime.
I have two criticisms. First, in a few spots, the dialogue gets a little confusing. This is usually the result of several characters all participating in the same conversation, making it difficult to keep up with who is saying what. These cases are rare, however, so they don't really detract.
Second, I'm disappointed that Galileo winds up being crazy. It seems like too easy an out, a little too tidy. As the only such element in the story, this stands out even more. It smacks of the only shortcut in a book that otherwise avoids them.
Those criticisms are minor, though. These tiny flaws did not interfere with my enjoyment of the story. I highly recommend this book. If the other stories in the series are as good, I'll definitely be looking for them.
