They live as outcasts, hated and feared by the very humanity they protect. They are mutants, born with strange and wonderful powers that set them apart from the rest of the human race. Under the tutelage of Professor Charles Xavier, they are more than mutants. They are the X-Men. Magneto, the X-Men's oldest, deadliest foe, has taken over the entire island of Manhattan and declared it a haven for mutants. Ruled by Magneto and his Acolytes, and enforced by reprogrammed Sentinels—powerful giant robots—the haven is the first step in Magneto's ultimate goal of world domination: the Mutant Empire. Now only the X-Men stand between Magneto and that goal. But the road to victory will not be an easy one, as half the X-Men are trapped in space—and mutants from all over the world are flocking to Manhattan and taking Magneto's side against the X-Men. This electrifying new novel by acclaimed author Christopher Golden is the ultimate adventure that no X-fan should be without!
