Query: Masterpiece

This is the first Clany book I've read and I have to say it's perfect. This is a true novel. He goes from discussing history with a Georgetown professor, to blowing someone's head off, and then to passionate love making in a single stroke. It's just incredible. This is one of, if not the, best books I've ever read. I'm 17 and enjoyed every word. Keep up the good work. I recommeneded this to everyone including my AP English teacher. She typically hates works of this genre, but couldn't put this book down.
