This book so far is not as intruiging as Angels and Demons, The Da Vinci Code and Digital Fortress. 
 But this is very informative for me as a non-historical person at all. This did not even keep me from putting this down a number of times since I started reading. But this book is doing quite well and is improving as I am now getting deeper into the story. I admit I am not even halfway through the story. 
 Nevertheless, this Robert Langdon book is a MUST READ still.
