Astonishing X-Men #21

In "Unstoppable Part Three," Joss Whedon and John Cassaday deliver a pulse-pounding chapter of Astonishing X-Men, where Wolverine and Armor reunite with Cyclops, Emma Frost, and the rest of the team amid mounting evidence that Colossus and Shadowcat are still alive. As the group splits to search for answers—Beast and Agent Brand braving a deadly snowstorm, Cyclops and Emma facing off against Danger, and Wolverine and Armor racing to find their missing teammates—the mystery deepens with a shocking betrayal and a mysterious sanctuary on Breakworld, where Colossus and Shadowcat are taken in by a woman named Aghanne, who believes their arrival may fulfill an ancient prophecy. The cover by John Cassaday captures the tension with a striking, intimate moment between two of the team’s most enduring figures.
