I'm a huge fan of Dan Brown -- or maybe i'm a fan of his indepth exploration of art history in different continents! Anyways, this novel was a good read -- typical plot setting with typical twists at random chapters. It's entertaining because Robert Langdon as a character is soo smart & equally amusing! But if you have read his other novels, you can easily connect the dots to who the main culprit maybe halfway through! I loved how Dan Brown stepped up a notch from his renaissance obsession and moved to Turkey -- reading about Hagia Sophia or the Blue Mosque were my favorite parts! 
 However, the way the twists were unfolding and thrown at Robert Langdon's face in the end were quite dismal -- it was done in such a hollywood-lazy-fashion sense & immaturely compared to the whole concept of the book! I really lost interest and couldn't wait for the book to end. & daaang, the way it ended -- say what? I can't enclose any spoilers but JESUS, really? The ending was downright lame and infuriating! 
 Now, I'm eager to know what his next book is going to be about -- dinosaurs perhaps?
