This is not the kind of book where you fall every day ... and it's a shame. This charming romantic pavement whose Fiordalisa is only a thread takes us above all in the Euro-Mediterranean history from the time of St. Louis. This is a virtual reality novel: the author manages the feat of us back into the power relations and the culture of the time, by tracing a very modern style on a story of a great documentary wealth. At the end of each chapter, a documentary addendum recalls the historical veracity; This will avoid the pitfalls in the "Da Vinci Code" where reality merged with the imagination to the point that I had to dive back into the reference books. None of that here, and culture adds to the pleasure of reading. In the novel, we find little intrigues because history furnishes suffisemment. The result is a good holiday novel, which is waiting for the second volume.
