Civil War : X-Men

This is the story of the feat that all men have of those who are different. It is the story of the hatred that keeps one race of people from living in peace with another. And it is the story of a dream—and what it would cost to fulfill this dream of peace between mankind and a new race whose very existence may sound the extinction of mankind. Join writer Joe Casey and artists Steve Rude, Paul Smith, Michael Ryan, and Essad Ribic for not only the origin of the race of humanity known as Homo Superior, but the beginning of the days of the X-Men. Collected here for the first time is the landmark first story of the world's greatest heroes.
