This is another book that follows the "Dan Brown" formula. If you like the formula (the "robert gets himself into a 24h adventure " formula) then you will like the book.

Plot wise, it was phenomenal. At first I was very skeptical about the plot, because some things didn't make logical sense to emit was like Dan ran out of ideas. But at the end when the plot twist is being revealed, I was shocked. It was intense. Everything made perfect sense about the characters and their motives.So,plot wise and story telling wise ,it was another great work by Dan

The thing I don't like about the book, was the fact it seemed "preachy". Every book of Dan has religious messages but this one was extreme. To the point I skipped those pages.

Overall, it was an absolute thrilling reading experience. I believe I finished the book in about a week or so.

Final verdict (by me ): 4/5
