"Angels and Demons" by Dan Brown

Was this book written by a different author than The Da Vinci Code? It sure seems like it. I previously read The Da Vinci Code. I enjoyed the story, but I thought that Dan Brown was a very poor author. Angels and Demons on the other-hand, is a very good book. You get the same element of half-fact, half-fiction that adds a lot of depth to the book. I found myself reading the book with my laptop on hand so I could check what elements of the story were in fact true. It was a great read.
