I enjoyed the book, but I liked Angels and Demons better. Dan Brown does come up with some interesting premisses for his books. He's not the best writer in the world, but his work is entertaining, and that's the point of a thriller I guess. The best review I heard of the book was "The worst book you'll ever love". Summed it up for me.

Dan Brown's has links to photos of many of the art work included in both Angels and Demons and The DaVinci Code. Some cool stuff there, like the Path of Illumination, the pyramids and the Grand Galley at the Louvre, and some other stuff. Oh, and a link to the guy that designed those awesome ambigrams.
