Hope was raised in the future by Cable, and now the two have returned! But the Human League is bent on eradicating Earth's final mutants - and they see Hope's death as the final nail in the coffin. As Bastion and his allies unleash a merciless all-out assault on the X-Men, everything rests on Hope's shoulders. Will this be mutantkind's end?
