Books with title Transformers: The Quest for the Allspark

When Sam learns that dueling factions of an alien race, the Autobots and the Decepticons, are bringing their battle to Earth, he knows he must do what he can to save humanity. But he can't do it alone—it will take the help of the United States government and a team of code-cracking scientists to prevent the Decepticons from getting control of the Allspark. Will Sam be able to stop the Decepticons from taking over the world, or will the Allspark fall into the wrong hands?
