New York Times best-selling author James Robinson writes the Eisner Award-nominated adventures of a new and more aggressive Justice League, led by Green Lantern. What brings a team together? Justice! Batman and Martian Manhunter have been slaughtered, and they're not the only heroes to fall at the hands of villains. The murder has to stop, and it's time to take the fight to the bad guys! Green Lantern, Green Arrow, Supergirl, Atom, Shazam, Congorilla, and Starman unite in a cry for justice! This graphic novel, written by James Robinson (STARMAN, SUPERMAN), with rising star artist Mauro Cascioli (TRIALS OF SHAZAM), pushes our heroes to the brink and beyond, as evil can no longer be tolerated. But when Prometheus plans his revenge on not only the heroes, but on the very places they call home, will this new team be ready to pay the cost for the justice they seek? This time it's personal-and it'll only get more bloody before it's over!
