I really enjoyed this book. It was semi-hard science fiction. The story was a very interesting one even if the characters were a little wooden.

In many areas the story holds up well, but there are some areas that it did not age so well. For one thing, there's no mention of DNA testing and much of the testing that takes place would be easily answered with a single DNA test. The prevalence of smoking in the story was distracting as well, especially in those situations where it would obviously not be allowed due to common sense (e.g. spaceships).
