After reading Angels And Demons, and hearing all the hype over the movie, I wanted to read this book. I saw the movie first, which was good, then read the book. I liked the book. As usual, Dan Brown fills it with twists and turns and codes and clues, it's great. It really made me wonder just how much of what he talks about is actually true. I'd love to meet him and ask. Read the book, watch the movie, and be entertained.
