"The icons of the DC Universe - Superman, Batman, Wonder Woman, The Flash, Green Lantern, Aquaman, and Martian Manhunter - are Earth's first line of defense against the high-priority threats facing mankind. But even as powerful as they are, and with an expanded membership in tow, the JLA is put to the test against their greatest adversaries yet: Lex Luther and his Injustice Gang, the all-powerful Darkseid, and a brand-new villain, Prometheus, who has everything it takes to kill the Justice League."--Page 4 of cover.
