Longtime X-foe Lady Deathstrike returns – while Karima struggles to remember herself, Rachel comes to terms with her relationship with Sublime, and a new member joins the team!

Recruiting the likes of Typhoid Mary and Enchantress, Deathstrike’s cabal goes on a global hunt for the most powerful ally of all – an enemy who holds the X-Men responsible for her near-destruction!
