If you liked The DaVinci Code, then you will LOVE Dan Brown's Angels and Demons. This was actually written before The Davinci Code and Robert Langdon's character, professor of iconology at Harvard University, is introduced in this novel. I have now read all of Dan Brown's books and although I agree that they are formulaic, they still hook me, every time! By the very end I had a good suspicion as to who the killer was, mainly because after reading The DVC I had a good idea where he would go with this one. I still loved it, though. Love the science, history and religion intertwined in the mystery!
