Injustice Gods Among Us. Year three. Volume 1

"There was a great and terrible war between heroes. On one side Superman and his Justice League, with their allies the Sinestro Corps, who sought to bring peace through absolute order. On the other side, Batman's army and the Green Lantern Corps. It ended with Superman wielding a fear-powered yellow ring, murdering Black Canary while the world looked on. But Batman lived to fight another day ... and Batman always has a back-up plan. Only one force in the world can hurt a Kryptonian wielding a Sinestro Corps ring-- magic. Now, with John Constantine seeking his own revenge against Superman, the sorcerer con man is helping Batman add the greatest magicians in the universe to his growing army. With the most powerful magic users in the universe on their side, Superman shouldn't stand a chance. And yet ... something mysterious is protecting the Justice League. Something that wants to protect Superman's vision of a world under his control ... and something deadly enough to kill some of the most powerful beings in the universe"--Page 4 of cover.
