Merenptah - Fall of the House of Ramesses, #1

Egypt was at the height of its powers in the days of Ramesses the Great, a young king who confidently predicted his House would last for a Thousand Years. Sixty years later, he was still on the throne. One by one, his heirs had died and the survivors had become old men. When Ramesses at last died, he left a stagnant kingdom and his throne to an old man--Merenptah. What followed laid the groundwork for a nation ripped apart by civil war.
The House of Ramesses is in the hands of an old man. King Merenptah wants to leave the kingdom to his younger son, Seti, but northern tribes in Egypt rebel and join forces with the Sea Peoples, invading from the north. In the south, the king's eldest son Messuwy is angered at being passed over in favour of the younger son...and plots to rid himself of his father and brother.
