Uncanny X-Men by Kieron Gillen Omnibus

Kieron Gillen masterminds a tumultuous era for the X-Men!Beast and Abigail Brand must save the alien-monitoring S.W.O.R.D. agency when Henry Peter Gyrich stages a coup! But down on Earth, how will the X-Men explain themselves when the public learns Magneto has joined the team? Making matters worse, a Breakworld warship arrives on a vengeance-filled mission — and when Asgardian black magic empowers the Juggernaut, he becomes more unstoppable than ever! Then, after the X-Men are torn in two, Cyclops leads a new “Extinction Team” of heavy hitters — including Storm, Emma Frost, Namor, Colossus, Magik and Magneto! And not moment too soon as world-ending threats are mounting quickly — including Mister Sinister harnessing the power of a Dreaming Celestial!
