Chris Claremont teams with a new series artist, Marvel legend John Romita Jr., in this massive Omnibus collection of the X-Men's uncanniest adventures! Milestones abound - including a descent into the Morlocks' mutant underground; a bruising battle between Colossus and Juggernaut; and the introduction of Rachel Summers, Cyclops' future daughter from "Days of Future Past"! Rogue emerges as a featured player, while Storm suffers a devastating loss! And it's all set against a rising tide of anti-mutant hysteria that threatens to strip every mutant in the United States of their rights.
