The Guardsmen did not start this war, but they will do everything they can to end it once and for all. The Mogadorians have invaded Earth and the Guard is all that stands in the way, but they will need an army of their own to win this battle. They have teamed up with the US military, but that may not be enough. The guardsmen need reinforcements, and they found them in the most unexpected place. Teenagers from all over the world, like John Smith's best friend, Sam, have developed powers. So John and the others must get to them before the Mogs, because if they don't, their enemies will use these gifted teenagers for their own evil plan. But after everything that was taken from John - his home, his family, his friends and the person he loves the most, he may not want to put lives in danger. He has nothing to lose and has just discovered that he has an incredible new legacy. Now he can turn himself into the ultimate weapon. So will he risk his life to save the world, or will he realize that strength in numbers will save us all?
