ON THE RUN AMONG THE STARS! JEAN GREY has been going toe-to-toe with some of the universe's toughest foes... but now a new threat is brutally asserting his dangerous reputation: none other than THANOS. And while she single-handedly battled back the BLACK ORDER, their nefarious progenitor (and his mysterious connection to Jean's many galactic enemies!) is another story entirely. To have a hope of victory, PHOENIX will need to reach out — beyond the limits of her own powers — and find allies to take a stand against the Mad Titan!
