Green Lantern Corps: The Edge of Oblivion #5
Time is running out. The universe is collapsing-and the Green Lantern Corps must find a way to survive! The last thing they need now is a war. But, even though the universe only has days, it seems the Corps are determined to destroy themselves faster than that. It's friend against friend. Teammate against teammate. And, if one side wins, thousands of innocents will be lost.
