Big action. Big Science. And a big mystery to solve! The superstar team of Warren Ellis and Simone Bianchi take the X-Men to the "Second Stage"! "Messiah CompleX" pulled the X-Men team together, "Divided We Stand" tore them apart. Now the X-Men are back to business -- with a new look, a new base of operations, and a mission that will take them into mind-bending and previously uncharted territory -- one that will test them -- and their leader Cyclops -- to their very core. You won't believe your eyes.
