In a world lost in a nightmare, Earth's greatest champions must awaken to remember their true identities, reclaim their powers and discover that together they are, now and forever- From acclaimed writer MARK WAID-the Eisner Award-winning author of seminal works including KINGDOM COME, SUPERMAN: BIRTHRIGHT and celebrated runs on Daredevil and The FLASH-comes this classic Justice League tale that serves as a precursor to one of the greatest comics runs of all time!
