This looks like a very interesting and competent book. It details the trade patterns between the Indus Valley Harappa civilization and Ancient Egypt and Mesopotamia.
(Harappa is the earliest Indus Valley civilization, and is the third of the great ancient riverine civilizations; Mesopotamia and Egpt being first and second, respectively; and with the Yellow River in China being fourth).
This is all part of my efforts to determine whether Mesopotamia should be considered as a Mediterranean Culture. And clearly, it should not. The situation in Egypt is more ambiguous, as it does have a Mediterranean footprint -- but even here, it is only one of three feet.
