Hard not to feel caught up in the narrative structure of parallel stories that maintains a breathless suspense !! This book brilliantly mell reality to fiction in a smart thriller that takes us in religion, art, esotericism. Without bludgeon us in a condescending erudition, it can introduce us and to focus on different stories of religious Western esotericism. It would be a shame to take seriously all the information related in this book, certainly a novel inspired by the reality is not intended to be a guide of art or religious history, but some assertions are pure fiction and it is prudent to check some information rather than accept the affimations and assumptions of the author as gospel Word. In short a book to take it for what it is: A ROMAN !! And in this area do him justice, he will not mark the history of literature for its literary quality, it will enchant you with curiosity and suspense that will spark !!
