Scarab and her brother Smenkhkare are in exile in Nubia but are gathering an army to wrest control of Egypt from the boy king Tutankhamen and his controlling uncle, Ay. Meanwhile, the kingdoms are beset by internal troubles while the Amorites are pressing hard against the northern borders. Generals Horemheb and Paramessu must fight a war on two fronts while deciding where their loyalties lie—with the former king Smenkhkare or with the new young king in Thebes.

Smenkhkare and Scarab march on Thebes with their native army to meet the legions of Tutankhamen on the plains outside the city gates. As two brothers battle for supremacy and the throne of the Two Kingdoms, the fate of Egypt and the 18th dynasty hangs in the balance.
