Got it from the American brother.
To the negative commentators: i should remind you, that this book is more than 30 years old. First edition:1978. Old like me.
This is not a small period even for the archeology: after this date were found almost 500 of the popular Ugaritic letters and many of the Hittite letters and signs. The researchers of the period know what I mean.
So if you really wish to be engaged in a real battle, you have to attack Cline, Bietak, Woudhuizen, Yasur - Landau etc. They are the present day researchers in the field. Sanders is from another generation and she is still after the great names of the golden times of the egyptology - Breasted, Gardiner, and even older "paleolinguists", like De Roughe, Chabais etc. Even the Palestinian hypothesis is not hers, it is mentioned by the Champolion himself.
I find this book great. No one survey of the end of the bronze age can go without it. Her best additions to the theory are the involving of the Balkan peninsula and the urnfield derived cultures(should say, after Kimming) to the movement.
Yes, some ideas are doubtful, I found her idea to count the time of the expansion on the length of the road, divided to the velocity of a middle - sized ox-car, a little bit comic. But her guilt here is that she is a woman and she does not understand very well the strategy of war.
Still it is a new age into the sea people understanding. Nowadays, a old one, but very important at his time. I would say, the most important.
