Gadalla, as always in all his books, provides thorough, and factual details about the "origins" of the many aspects of Egyptian peoples and their civilization. Having said that, because many have not been priviledged to have read many of his writings, I think that he should highlight in every book, as he did in "Exiled Egyptians", who the people in that early epoch of Egypt (Kmt) were.
Most people don't realize these were "Black Africans", at this time period in Egyptian history as proven by their own statements of their origins, linguistics, archaeology, paeleontology, iconography, etc. Since this is still today not being taught throughout the world in the educational systems due to ignorance and racisim, it should be constantly empasized by those who "know". This is the true meaning of "Maat", to do, say, and be, what is right and just in the world.
