New Avengers by Brian Michael Bendis Vol. 5
Having barely survived their defeat of the Phoenix-powered X-Men, is it time for the New Avengers to call it quits? They may not have a choice in the matter: One after the other, the most powerful sorcerers on Earth are being slaughtered by a mystical force unknown even to Dr. Strange! But when this provocation from a mystical plane comes crashing to the doorstep of the Avengers mansion, does the former Master of the Mystic Arts have what it takes to stop the attack? Does anyone? Collecting NEW AVENGERS #31-34.
