But not even the combined power of Superman, Batman, Wonder Woman, Green Lantern and all their fellow superheroes can slow down the onslaught of this invincible horde. What mysterious force is driving them? And how do the long-buried secrets of the Monitor and Supergirl threaten to crush our last defense?
