This was my first by Sheldon and I must say, I really liked this book. I hadn't read anything like it before. This dispelled all those thoughts that the topic is more of a "mans read". It had a strong male character, involved government conspiracies, military..all the things that aren't my first pick in a book as it's usually over my head or doesn't hold my interest. Boy was I wrong. I was glued from start to finish. It will either make you wonder or you'll probably think the book ridiculous. If you like the Jason Bourne stories/movies, this is along the same lines.
