"The X-Women get their own book! An old enemy shows up at the X-Men's door, seeking asylum from an ancient evil. John Sublime is back, but he's not who we should be afraid of! Who or what is Arkea? Meanwhile, Jubilee returns home--with an orphaned baby who might hold the key to Earth's survival--or its destruction! Against a backdrop of what seems like an alien invasion and an eons-spanning war between brother and sister, Storm puts together a team to protect the child and stop a new threat that could destroy all life on the planet!"--Back cover.
