Sixteen million mutants dead...and that was just the beginning. In one bold stroke, writer Grant Morrison (The Invisibles, JLA, Fantastic Four: 1234) propelled the X-Men into the 21st century - masterminding a challenging new direction for Marvel's mutant heroes that began with the destruction of Genosha and never let up. Regarded as the most innovative thinker of the current comic-book renaissance, Morrison proceeded to turn the mutant-hero genre on its ear. Gone were the gaudy spandex costumes - replaced by slick, black leather and an attitude to match. Now, his entire Eisner Award\-nominated run on New X-Men is collected in one Omnibus.

She brought an interstellar empire to its knees. Can even the X-Men hope to halt her mad rampage?

His name is Charles Xavier … and he is a mutant. For years, Professor X was widely regarded as an authority on genetic mutation, and an advocate of peaceful relations between man and mutant. The general public was unaware he possessed superhuman powers until the psionically empowered Cassandra Nova—his twin sister—addresses the global media while in possession of her brother's body and broke the decades-long silence. But in attempting to expose Xavier to his enemies, she unwittingly freed him from his self-imposed exile. From the teeming city streets of New York's Mutant Town to the irradiated ruins of the island nation of Genosha, once a haven for mutants, the X-Men set off to heal the rift between humanity and Homo Superior—only to discover a terrifying new threat from a new species!
