The greatest threats come from within. The X-Men have emerged victorious from the fight of their lives, narrowly defeating Bastion and his army of Nimrod Sentinels. But the wounds run deep--and when one X-Man loses control, another does the unthinkable in realiation. Then, following the shocking events of Age of X, the X-Men are left with memories of lives unlived and feelings never felt. Can the team pull together after witnessing the unimaginable, or will the burden of these recollections be too much for the X-Men to bear? COLLECTING: X-MEN LEGACY #242-244 and #248-249.
