Dan Brown sure knows how to write a thriller! The story was interesting - taking rituals, science, artwork, Washington D.C monuments and wrapping you up page after page! 
 The first half of the book was crazy interesting and it was hard to put down. Half the time I wanted to get on a plane to Washington D.C. so that I could see all these amazing places and objects in person! I even found myself Googling some references so that I could really visualize what was happening in the story! 
 Although not at first, I found myself being a little disappointed with the "evil" character. While catching at first, he got to be a little predictable - and I even saw coming the "twist" in his identity. 
 All in all a really good read and I expected nothing less!
