The Valley of the Kings - Cecelia Holland
So this basically two novellas. The first, about Carter finding Tut's tomb, is pretty good. It also includes the conflict between Egyptians and those who would steal their heritage.

The second part, set in Tut's time, is really not good. In part, this is because of the change in knowledge about the time period from when the book was first written, but also in part because the plotting is basically a mess there.
