Query: A great first novel...

I previously read several Steve Berry books from his Cotton Malone series. They were good enough to keep me coming back for more, so I decided to start at the beginning. The Amber Room is not a Cotton Malone story, but a stand alone novel. It is Steve Berry's first published novel and, considering this, a surprisingly good effort. I think it's my favorite Steve Berry book to date.
