Publisher Description.  The X-Men's new era is fully underway, and starting this December, fans will experience an epic crossover between two of its three flagship titles in Raid on Graymalkin!

Left broken and scattered in the wake of Krakoa, the X-Men have since regrouped into distinct teams of their own.  In Jed MacKay and Ryan Stegman's X-Men, Cyclops leads a squad of hardened mutant soldiers out of an abandoned Sentinel factory in Alaska.  While in Gail Simone and David Marquez's Uncanny X-Men, Rogue attempts to build a new home with her chosen X-family along with a handful of new students down in Louisiana.  Their different approaches to the X-Men's mission erupts into a tense standoff when a plan of action is needed to take down Graymalkin Prison, formerly Xavier's Institute!

The X-Men’s school has been transformed into a brutal penitentiary for mutants by the callous Dr. Corina Ellis, and her prize inmate is none other than Professor X himself!  But after his actions during Krakoa's fall, is Professor X worth saving?  And who or what is the secret weapon that Ellis is confident will protect Graymalkin against any attack?  Find out in this four-part mutant milestone that solidifies the X-Men's post-Krakoan world!
