Threats multiply in the Reign of X! As Cable and his allies draw closer to the secret of the missing mutant baby, a fateful reckoning draws ever closer! The origin of the Children of the Atom is revealed — but who really are these junior X-Men behind their masks? And a brand new alternative medicine starts to change lives at their school, but who’s recruiting the patients…or should that be victims? Meanwhile, an invisible threat is loose on the island of Krakoa — unseen, unheard, undetectable by any…except Excalibur. Elsewhere, one of the deadliest enemies in the history — and future — of the X-Men comes online. And when Mister Sinister goes missing, can the Hellions unravel the mystery?
