I believe people say this is Dan Brown's weakest book? I beg to differ. I quite liked this one, or at least the subject it was about. And I think now with all the commotion on the NSA and Snowden, it's again a hot topic. How much privacy should we give up in order to achieve safety? What is this safety?
Perfectly in Dan Brown style, there is a lot of running, shooting, (almost) killing, etc. I never really like too much of those things in my books, because it tends to become predictable very fast. Still, I've eventually read the first five Dan Brown novels, because people kept asking me whether I had already read them.
Note: I read a Dutch translation of this book
