Cannonball, Dani Moonstar, Karma, Sunspot, Magma and Magik have put the band back together - just don't call them the New Mutants! They might not get to be old mutants either, when one of the most powerful threats they have ever faced returns - Legion! Speaking of comebacks, the dead just won't stay dead as the shocking events of Necrosha hit home...and Doug Ramsey and Warlock return to the fold! The team's past returns to haunt them as they are dragged into the hellish dimension of Limbo, but will the secret they uncover there lead to the fall of the New Mutants once and for all?
