One of the most explosive sagas in comics history! Peter Parker's world is rocked like never before by the return of his clone, long thought dead. For years, the clone has lived in peace as "Ben Reilly," but now he'll be drawn back into wall-crawling action as the Scarlet Spider! But who or what is Kaine? Both Peter and Ben are caught in a web of death spun by the Jackal, and their power and responsibility will be tested to the limits as the villain's game of smoke and mirrors raises the question: Just who is the real Amazing Spider-Man?
