This comprehensive, 2-volume book about the Ancient Near East clearly has some outstanding points in its favor, but sadly also several serious drawbacks.
On the upside, there is not too much more you would want to know about the history of Anatolia or Mesopotamia in the timeframe covered, unless you are upper division college student in history or archeology. The book gives a painstaking account of all major sources, has an outstanding bibliography, and the author certainly went to great lengths to portray pro's and con's of various interpretations to points of contentions regarding the interpretation of historic evidence in general, and in particular while discussing specific sites, possible historical outlines of a region etc.
Be advised though, that the coverage of areas like Egypt, Eastern Iran or Afghanistan, to name a few, is by far not as substantial as that of the other two.
If, on the other hand, you are not a student in aforementioned subjects, or at least a very interested layperson with a previous solid foundation in the science, and simply want an overview of the regional history, this is not your book.
Among several things that will be unsatisfying for you are her endless enumeration of sources (incredibly boring, unless you actually have access to those), a constant jumping from region to region, which makes sense on the one hand, but is not exactly enhancing the readability for the casual reader.
Another very unsatisfying aspect, and maybe even one of the worst parts of the book, while having the general reader in mind at this point, but also to some extend to the more informed reader, are the maps. While there are quite a number of them, their quality is, to put it mildly, pitiful. Many don't name the real points of interest (as for example it would be nice to have the maps actually show the sites she discusses in the text that refers to them), they never show any regional boundaries, as to make clear for example where, when, who was in charge of what territory. Also don't hope for anything like a timeline, or other features that will help the lay reader to follow more easily the course of her presentation.
To sum it up, a book with good use for the serious student of the subject, while only of limited, if any, interest for the layperson.
