This book doesn't deserve all the praise it's getting.
It is a very exciting book, with a cliffhanger ending to every chapter and very short chapters.
I felt It was poorly written and a duplicate of every other book Dan Brown's ever written. For the accuracy of this book, I think that it plays well to tell readers that most of the findings in the book are fact. I don't believe they are. Remember, they also told us that the Blair Witch Project was a documentary. It makes it easier for the reader to be involved in the story if they believe it to be somewhat true.

I would not recommend this book.
