Chris Claremont, the man who made Marvel's mutants an industry unto themselves, takes the X-Men to hell and back - and damnation couldn't look any better than with legends Marc Silvestri and Walter Simonson behind the art boards! The "Inferno" saga brings together the many threads Mister Sinister has been weaving, the machinations of the demon N'astirh, and the lives of X-Men past and present. In one of Marvel's most devastatingly personal epics, the startling secret of Madelyne Pryor is revealed - and the X-Men and X-Factor will face each other for the first time! This newly restored edition also features the return of the alien Brood, the introduction of Genosha and a Savage Land adventure drawn by Arthur Adams! Collecting UNCANNY X-MEN (1981) #232-243, X-MEN ANNUAL (1970) #12 and X-FACTOR (1986) #37-39.
