Query: Unsatisfactory

The book has a great collection of maps; however, sidetracks from major aspects of Egyptian history. The information presented on the 25th Dynasty, is particularly unsatisfactory. Major events like the battle of 701 BC between Egypt's 25th Dynasty and Assyria, which changed map of the middle east, is vaguely mentioned. The information presented is inconsistent and certainly unsatisfactory for the average reader.
