In Chicago, John makes the unlikeliest of allies: a Mogadorian named Adam, who has switched sides. Adam knows the Mogs secrets, and he knows where to hit them: their command base near Washington, DC. But during the assault, John learns he and the Garde might be too late. The Mogadorians have commenced their ultimate invasion plans.

Meanwhile, Six, Nine, and Marina make their way through the Florida Everglades, hot on the trail of the traitorous Five. With the development of a new Legacy, Marina finally has the power to fight back--if her thirst for revenge doesn't consume her first. The Garde may be broken and divided once more, but they will not be defeated. As long as one still stands, the battle for Earth's survival is not lost.
