*John Byrne's FF endeavors end in era-transcending odysseys when the World's Greatest Super-Team ventures into the Negative Zone, a remade past and a future sculpted around the FF itself! Plus, the death, life and rebirth (not necessarily in that order) of Doctor Doom! Guest-starring Nick Fury, the Avengers and the Beyonder! *Source: marvel.com
