Dead X-Men #2 (Fall of the House of X)

THE IMPOSSIBLE TEAM ON AN IMPOSSIBLE QUEST! The Dead X-Men leap across time and space in a last-ditch effort to prevent catastrophe, but they're not the only ones breaking through the fabric of reality! As these five mutants go places no one has gone before, a cloaked figure stalks them from the shadows…and nothing will survive if she reaches her goal! Rated T+
