After bringing together the weirdest, wildest, must unlikely Justice League roster ever assembled, the Dark Knight Detective has quit the team. Now it's up to Vixen, the JLA's powerful but unproven new leader, to give the group a reason to stay together—without ending up at each other's throats. She had better do it quickly, though, because one of the deadliest villains in the League's history has just returned. His name is Prometheus, and he comes to the team's Happy Harbor headquarters with a simple Vixen must face him in single combat, or everybody dies—and with his new psychic ally Afterthought at his side, there's no way he can lose. But not even a master tactician and genius-level strategist like Prometheus can predict the behavior of the JLA's own secret weapon—the Main Man himself, Lobo. When the smoke from their final showdown clears, who will be left standing? Find out in Justice League of America Vol. 4: Surgical Strike, from the acclaimed creative team of writer Steve Orlando and artists Hugo Petrus and Stephen Byrne, and featuring a special guest appearance by comics legend Kelley Jones.
