If you have a high tolerance for heresy, this is a really interesting book. I'm not fully qualified to disagree with the premises, although the literary scholar in me is a bit appalled at the jumps made from the contents of the texts to the circumstances of their authorship. Literary archeology is interesting, but I'm not sure how behind it I'm willing to get.
Having said that, the way that Zakovitch fits the sociocultural elements of the ancient world together with the text and examines how different biblical stories relate to and draw on one another is very cool and it was worth reading for that.
I just wish it had...a point, perhaps? I mean, much of the point was "look at what I can do!", which is not a bad scholarly endeavor. But, as the Little Mermaid says, "I want more." Zakovitch writes a biography of a ficitonal(ized) character and I expect literary analysis to go somewhere. Where exactly is this supposed to be headed?
