Transformers: Revenge of the Fallen (Transformers (Ballantine Books))

"THE FALLEN SHALL RISE AGAIN. . . ."
This cryptic warning is ignored by the national security adviser who feels the ruthless Decepticon threat is no more. The allies are victorious, the enemy has been defeated, and the world is safe. Small attacks around the world have been contained, and the remaining pieces of the coveted Allspark are locked in an electromagnetic vault on one of the most secure Naval bases in the world. But nothing is at it seems, and there is a shift in the shadows. Things can change in an instant-and fragile peace will become all-out war.
