The second adventure in the Joss Whedon-John Cassaday production finds the X-Men fighting an enemy from inside their own ranks that only wants one thing: to kill the X-Men. As the team fights for their lives they know things will never be the same again.

Whedon and Cassaday's final chapter in the series finds the X-Men saving the Earth from destruction at the hands of the Breakworld. When it's all over the team will find that nothing is the same and that they're more than Astonishing...they're UNSTOPPABLE!
