Superman/Batman Vol. 7

From Michael Green and Mike Johnson, two of the writers of the hit NBC TV series Heroes, comes this fast-paced new volume in the SUPERMAN/BATMAN series.
The Man of Steel and the Dark Knight have decided that they must undertake the impossible task of recovering all the Kryptonite on Earth. But there are plenty of roadblocks in the way, as they realize that not everyone's willing to hand over the deadly substance. And one of those who's not ready to cooperate is none other than their fellow Justice League member, Aquaman.
