I still like this book better than The DaVinci Code.
Read this after the DaVinci Code and A and was still pretty impressed for this being one of his older works. Skip Digital Fortress though, his first book (you can tell it was his first!).
The Great Gatsby
Water for Elephants by Sara Gruen
The Sookie Stackhouse aka True Blood series
Dan Brown - Deception Point
The Time Travelers Wife
