Uncanny X-Men by Gail Simone Vol. 4: Where Monsters Dwell

The daughter of darkness herself, Mutina, interrupts a festive event! She has an unimaginable favor to ask the Uncanny X-Men, and woe betide them all if they refuse! It's murderous mutants and cake and blades, and you'll look very differently at one of the core X-Men after this bloody issue! A forgotten vow from one of the team comes back to haunt them all in the most shocking way imaginable as ghastly guest stars from Marvel's past threaten to take one of our most beloved mutants into their number forever! Can the X-Men stop their friend from being taken to Where Monsters Dwell?
