Uncanny X-Men: Lovelorn
In the depths of his heartache over Kitty Pryde, Colossus goes looking for something -- anything -- to stop his pain... and finds a nightmare from the Old Country running rampant in the States. What's their connection? Elsewhere, Angel and the Beast begin a worldwide quest gathering some of the most unique minds on Earth and run across a hero long thought dormant.
