You're either interested in this topic or not, but if the question is whether this book is good at that topic, then yes, it is. It's very good.
It packs a lot of information into a quite short book.
It's in four broad sections. The first is an introduction and outline of Egyptian history. The second is a narrative "history" of Egyptian myth, beginning with the creation of the world and moving through the retreat of the goddess and the contention between Horus and Seth, and so on. The chapters here indicate how many different gods could fulfill the roles of each narrative event.
The third section is an A-Z of gods, places, and groups, often filling in the narrative from the previous section. The final section is an extensive bibliography.
