One of my favorite book series is by Dan Brown. The Lost Symbol, The Da Vinci Code, Angels and Demons, Inferno are all some of my favorites. I actually have the Da Vinci Code in multiple prints! His writing style is carried on in his novel, Digital Fortress, but my love for the Character of Robert Langdon prevents me from enjoying that one too much. I think it is the mystique, the puzzles, the exhilarating chases, and the history in the novels that captivates me so. To imagine such a clandestine set of events that occur without anyone bothering to notice intrigues me I suppose haha! All in all, these are my personal favorites! I highly suggest reading them before watching the movies since, as always, the book is WAY better than the movie!
