The Fate of Ten - Pittacus Lore
Even as the giant ships filled with Mogadorian soldiers loomed over two dozen human cities, John Smith (title character of I am Number Four) and his faithful friend Samwise… err, Sam bring the powers vested in them by the elders of Lorien to bear against the evil Setrakus RĂ¡. As the two BFFs battle pasty-faced Mogs in the streets of NYC; Six, Seven (aka Marina) and the trueborn Mogadorian Adam who channels One find themselves in a pitched battle with other Mogs at an ancient temple in the Central American jungle. That leaves only Five and Nine, the remaining Garde, who battle against each other high above Manhattan.

Sam’s beloved Sarah and his high-school nemesis, Mark, have joined forces with The Navigator in what looks as though it will be a losing cause: ten or so teens and one adult, arrayed against a gazillion evil aliens led by a shape-changing ghoul who can blank the Garde's legacy powers with a twist of a wrist? But wait… suddenly, teens (and only teens – this is, YA, after all) around the world have suddenly begun developing Legacies of their own.
But why? How? And more to the point, is it too late? Read The Fate of Ten and perhaps you’ll find out…
