In my opinion, it would be really hard to write a book as good as either the Da Vinci Code or the Angels and Demons, but this book didn't even come close. The only reason I didn't put it down after reading the first half because I like to finish the books I start. The first half was boooooring! I wanted to read about the secrets hidden in the 500 year old book not about life on campus at Princeton. And I had to go back some pages a few times too as I got confused about who was who? It did get better in the second half, a little more exciting, but I'm glad it wasn't any longer :)
