I am currently reading the prequel to the Da Vinci Code, Angels & Demons by Dan Brown. Angels & Demons follows Harvard symbologist Robert Langdon, as he tries to stop what seems to be the Illuminati, a legendary secret society, from destroying the Vatican City with the newly-discovered power of antimatter. Many who have read it say it is better than the Da Vinci code. It is definitely a page turner. Both books take place within a 24 hour period. Short chapters read quickly; it's like watching scenes of a movie. I highly recommend Angels & Demons.
