The event that the New 52 has been building towards since the beginning! Writer Geoff Johns brings together almost two years of plot threads for an epic tale that will forever change the shape of the DC Universe. When the three Justice Leagues (Justice League, Justice League of America, and Justice League Dark) go to war with one another, who's side will everyone be on? Allies will be born, friends will become enemies and the DC Universe will never be the same. -- Provided by publisher.
