Transformers: Revenge of the Fallen: Alliance, Volume 1

In graphic novel format, from the distant planet of Cybertron, an alien race continues their ongoing battle on Earth. Their goal is to obtain an ancient artifact known as the Allspark. Though the Autobots would claim victory, their isolation on Earth could leave them weakened and vulnerable. Their only hope for survival could rest in the hands of a few humans they have befriended. With the Decepticons far from defeated, forming an alliance and working together could be the only way to survive.
