I finished the whole series in two days. Granted, I had a lot of time on my hands. When I say there was a lot of action, there was a lot of action. Seriously, you didn't have a chance to breathe before someone was pulling out another gun. So in this series the protagonist has no serious flaw as far as the eye can see. He is perfect (except for the fact that everyone thinks he is evil). I don't really believe there is much of a deep message in there. It was pretty much America is awesome and never give up. Really it was a guy book to me. Don't go looking here for the answers to life's deep questions. But if you want an easy read with a lot of action and suspense, this series is for you.
