X-Men by Gerry Duggan. Vol. 5

In the shocking wake of the Hellfire Gala, what will the FALL OF X mean for the X-Men? For one of their greatest, it will change everything! She's been known as Kitty Pryde, Sprite, Ariel, Red Queen, Captain Kate and more. Now, out of tragedy and torment emerges…Shadowkat! But how will Kitty and her fellow mutants react when Emma Frost marries Tony Stark? And as wedding bells ring, where is Cyclops? Nowhere fun! Meanwhile, Juggernaut has come a long way from his beginnings as a bully transformed into an unstoppable foe. In fact, he'd recently become one of mutantkind's best human allies. So why is he trying to kill Firestar? And, with your favorite super-team at its lowest ebb, there's a new group looking to claim their mantle: meet Doctor Doom's Latverian X-Men!
