"Written 60 years ago and still a very good sci-fi"
The story stands the test of time! I was hooked after the first two chapters. My mind was constantly working trying to figuring out what the next chapter would bring. When I finished the book, I purchased the second one immediately. If you’re a Larry Nevin or Jerry Pournelle fan you will most likely love this book. A few things to consider are that you have to on occasion suspend your critical eye as certain thing show this book was written in the 50s (everyone is smoking and some of the technology references date the book). Also the narrator was pretty good but sometimes did not change his intonation enough when changing character. Note that he improved this significantly in the second book and was no longer an issue for me.
