IN THE MAIL:

James D. Tabor, The Jesus Dynasty: The Hidden History of Jesus, His Royal Family, and the Birth of Christianity

Kindly sent to me by the author.

UPDATE: Follow the link above and scroll down for Tabor's review of the The Da Vinci Code movie. He also notes its tendency to correct errors in the book and he gives another good example that I'd forgotten. He liked it better as a movie than I did.
