Scarab-Smenkhkare. The Amarnan Kings, #2

King Akhenaten, distraught at the rebellion and exile of his beloved wife Nefertiti, withdraws from public life, content to leave the affairs of Egypt in the hands of his younger half-brother Smenkhkare. When Smenkhkare disappears on a hunting expedition, his sister Beketaten, known as Scarab, is forced to flee for her life. Finding refuge among her mother's people, the Khabiru, Scarab has resigned herself to a life in exile...until she hears that her brother Smenkhkare is still alive.
He is raising an army in Nubia to overthrow Ay and reclaim his throne. Scarab hurries south to join him as he confronts Ay and General Horemheb outside the gates of Thebes.
