Here is just my .02 worth:
Pharaohs of Ancient Egypt was a bit hard to get into at first for my dd, 11 but it finally caught on. We have been reading it together and have both found it fascinating! It actually has a lot in it about the culture -the pharaohs and pagan gods were, in my opinion, a central, if not the central part of the Egyptian culture. Just my thoughts – the other suggestions sound great too!
