Injustice: Gods Among Us Year Two, Book 2

A war is coming between heroes who were once friends. A war of gods. The stern dictator Superman has a new ally—the terrifying Sinestro Corps. The Guardians of the Universe are not pleased with Superman's actions and send the Green Lantern Corps to assist the alliance of heroes who have risen against his unjust regime. Everything, from the grandest cosmic force to the tiniest green bullet, will be used against the insane god. But death is not the only way to stop him.
