I bought this book for rave reviews and because it is in the best sales. But what a disappointment !! It has no depth, history and flat and a little ass ass, not credible or initiation. The idea is good but poorly defended by a narrative without any literary quality. I still remember with delight reading The Alchemist by Paulo Coelho, the book had really transformed me, while that of Gounelle has afflicted me. Reads in a few hours ... it's still much too!
