I loved the book. I thought it was extremely thought-provoking, and his underlying "conspiracy theory" holds a lot more water, imho, than any more modern ideas about conspiracy of, say, the TriLateral Commission, etc. It's more than a little unlikely that so many murders (those in the book) would be committed in order to keep the lid on an historical secret that has already been disclosed pretty widely, though. Still, the fictional mystery stuff made it a great page-turner, and the material about the suppression of the feminine by the patriarchal Catholic church is fascinating, still very relevant and under-reported, but old news. If Mary Magdalene really was the most beloved and important of Jesus' followers, if the Church had allowed and acknowledged that, then women could obviously be deacons or priestesses or whatever, could hold any office up to and including Pope, and there would never have been any medieval conferences to address the burning question of whether women had souls. Millions of women would not have been burned at the stake. Women might not have had to struggle so hard to get political rights, personal rights, property rights, etc. History would have been very different.
