I HAVE read Angels & Demons, and Davinci Code, and this book is vastly more entertaining than both of those. One additional note, is that those books were more entertaining than most of the "see how fast we can write" books coming out today. In reading the previous review, I am not sure if the author did the appropriate research on the NSA or not, but the reality is that it is FICTION. Just like Angels & Demons and The Davinci Code are FICTION. These books caused such a stir, only to fing out that it is all fictional, without a shred of truth.
I digress, the book is very entertaining, and I would recommend it to everyone.
