Query: Wonderful Thriller...

This novel was my first exposure to Mr. Brown. I had heard all of the hype concerning "The DaVinci Code", but realized that this book was the first in the Robert Langdon series, so I purchased it first. I must say that this was a wonderful book. There were so many times when I had to make myself put it down. It is very gripping and very intense. I am sold. The best way to describe this book is "well thought out". Dan Brown is a master.
