From the back cover: It takes a desperate man to attack the X-Men single-handed, but revenge for a murdered partner makes a man desperate. Did Wolverine really commit murder, or is he being set-up? The search for that answer sends the X-Men around the world, and puts them on the trail of their oldest enemy - Magneto, the Mutant Master of Magnetism! And (could it be) the Original Brotherhood of Evil Mutants! What's Maggie up to this time. And can the Uncanny X-Men stop him?
