The future Brotherhood of Evil Mutants, last seen in 'Battle of the Atom', are back-- and they're still gunning for yesterday's X-Men! But even as the Brotherhood take their next devastating step against the time-tossed teens, the mysteries surrounding Jean Grey begin to unfold! Jean came back from her Shi'ar trial different. What does this mean for her future, for the past of the woman she's supposed to become, and for the rest of the X-Men?
