n this trade paperback, the Universe's greatest heroes face two deadly threats that could mean both the end of the Justice League and the world. First, the Justice League must battle Mageddon, the doomsday weapon of the Old Gods, and prevent his attempt to end all of existence. Then Superman, Batman, Green Lantern, Flash, Wonder Woman, and the Martian Manhunter find themselves up against a new, deadlier Injustice Gang led by Lex Luthor. With the addition of Prometheus, the man who almost single-handedly defeated the JLA, as well as the General and Queen Bee, it looks as if the Justice League may lose even if they win.
