Kelsey Bandar and Jared Mertz must retrieve the electronic override buried under the ruins of the old Imperial Palace to win the war against the AIs. Oh, and get off the planet in spite of the murderous warships orbiting the destroyed world. How hard could that be? Imprisoned in a dead megacity and surrounded by howling savages thirsty for their blood, they must triumph or die. And if they die, humanity dies with them.
