Query: Not for light reading!

This book was a real struggle to read. For about 3/4 the author takes us through a morass of genealogies and accounts of old historical figures without really an end in sight. Just when I think I understand what he is trying to present, he jumps to a different subject, making me start all over. I was impressed by the amount of footnotes indicating thorough research, but it came across more as a college thesis with little effort to present the information in a readable fashion.It was not until the author presents The Hypothesis that the reading becomes compelling, then it ends too soon. Whether the facts the author presents lend credence to the hypothesis is up to the individual reader. Perhaps this is one of the works that began the phenomenon leading to the DaVinci Code, but I see that that there are other books on the market addressing the same subject, and I plan to read more of them. I would not really recommend this one as a starting point.
