Appalling and apoplectic. This is just another book touting the fantasies of the Priory of Sion.
Glad it was loaned to me.
It's a myth, actually, or a series of myths. There are very few facts and a lot of (often-extravagant) theories. The continuous reference to "Holy Blood, Holy Grail" is disturbing. But, wait, there is a good point: This book is a very good collection of all information surrounding the "Merovingian Mythos", so it is a quite interesting start for the beginner.
