"An alien army has returned... and they're not coming alone. With an aquatic army ready to destroy the Earth, the only thing standing between the planet and total annhilation is the King of Seven Seas, Aquaman, and the Justice League. Unfortunately, the World's Greatest Superheroes don't stand a chance. In the aftermath of the Justice League's battle with the Legion of Doom, an armada from the stars has come to plunder the Earth and its seas. With powers beyond comprehension, even Superman, Batman, Wonder Woman, Aquaman and the rest of the League's combined might can't stop these invaders. With nowhere left to turn, these heroes will have to turn to an ancient power to help them, one that even Arthur Curry fears unleashing."--
