I just finished reading The DaVinci Code and really enjoyed it. I liken it to the Indiana Jones stories. I think if you like Indiana Jones, you will like this book.
That said, if you are defensive about your christian beliefs, you probably won't like this book. It is all about pagan origins of christian beliefs. Interesting stuff but some might find it very offensive.
This story has so many twists and turns! The characters are so interesting and the descriptions of European churches, museums and artwork keeps you riveted. Anyone who enjoys a good riddle will enjoy this story. It is one of those books that I enjoyed reading so much that I was sorry to finish it.
