When an alien race arrives to claim ownership of Earth, the X-Men must find a way to repel them in this thrilling adventure novel.
The Kh'thon descend upon Earth not as invaders, but as the planet's rightful owners. They claim to have left millennia ago, and their evidence is startling: not only are their ships manned by Homo sapiens, but their will is enforced by specially augmented humans with phenomenal powers—and each one is a match for any of the X-Men.
According to the Kh'thon, they are the original creators of the X-Gene, which allowed them to breed their servants with whatever abilities they required. The Kh'thon believe that Earth belongs to them, as well as every being living on it—human and mutant.
Now it's up to Wolverine, Kitty Pryde, Nightcrawler, and the rest of the X-Men—together with Scott Summers, now a member of X-Force—to defeat the Kh'thon before they are enslaved by these would-be alien masters. . . .
