This book started on a flying, it is much greater than the Da Vinci Code that falls more or less the same themes ... A religious thriller mixing history and fantasy. Almost no dead time, which is rare ... the end is a little less hectic and more fouillie but we read this book from beginning to end, without taking off ... some scenes are indeed very hard, but so well described , we can not stop reading them, despite their very graphic descriptions .. A must read ...
