The premise of Dan Brown is really fun. The book starts well and makes the assumption that the author is completely original. By cons, trying too hard to stick a write mode taught in American universities, the book loses interest. And the reader ends up guessing in advance what that lie author. Unfortunately, the more we advance, the more we are disappointed. The author misses its end in starved of finesse on the description of his secret society and loses any literary credibility. It's a shame!
