«Out of the Black Land» by Kerry Greenwood

Eighteenth Dynasty Egypt is peaceful and prosperous under the dual rule of the Pharaohs Amenhotep III and IV, until the younger Pharaoh begins to dream new and terrifying dreams.Ptah-hotep, a young peasant boy studying to be a scribe, wants to live a simple life in a Nile hut with his lover Kheperren and their dog Wolf. But Amenhotep IV appoints him as Great Royal Scribe. Surrounded by bitterly envious rivals and enemies, how long will Ptah-hotep survive?The child-princess Mutnodjme sees her beautiful sister Nefertiti married off to the impotent young Amenhotep. But Nefertiti must bear royal children, so the ladies of the court devise a shocking plan.Kheperren, meanwhile, serves as scribe to the daring teenage General Horemheb. But while the Pharaoh's shrinking army guards the Land of the Nile from enemies on every border, a far greater menace impends.For, not content with his own devotion to one god alone, the newly-renamed Akhnaten plans to suppress the worship of all other gods in the Black Land.His horrified court soon realise that the Pharaoh is not merely deformed, but irretrievably mad; and that the biggest danger to the Empire is in the royal palace itself.
