STRANGE GETS TROLLED? STEPHEN STRANGE, the once Earth-bound Sorcerer Supreme, is in over his head - ASGARD is about to eat him alive! He needs the skull of a dark troll - and in Asgard, that means wading into battle. But can Strange do what Asgard requires of him, or is his mission to become Sorcerer Supreme of Asgard doomed?
