Heroes of the present and legends of the past come together to form the Justice Society of America! Now honored as heroes, the new JSA continues to endure the trials that made the Justice Society heroic icons. But as heroes continue, so must evil. Once again, the JSA is called upon to save the planet from malevolent forces that may threaten the very fiber of the universe! This collection has our heroes confronting the return of the Injustice Society, a darkness-consumed Obsidian and the time-shattering threat of Extant!
