Extraordinary X-Men (2015) #17

INHUMANS VS. X-MEN TIE-IN! � The X-Men have just learned that the Terrigen Mist-the source of the Inhumans' powers that through a cruel twist of fate is lethal to Mutants-has reached an irreversible saturation point, rendering Earth uninhabitable to their kind. � And now they see no other option than to strike against the Inhumans to ensure their own survival. � But one X-Man doesn't take the decision lightly. � STORM has literally led the X-Men through hell and back, but will she lead them against their longtime friends and allies? Rated T+
