And if that isn't cosmic enough for you, what would you say to Squirrel Girl jumping headfirst into the War of the Realms?! When Doreen's good pal Loki recruits her as part of a secret mission, you might wonder if he's up to something. And he probably is -- he's the God of Lies, after all. But this isn't Doreen's first Asgardian rodeo! And whose side is her old nemesis -- the Asgardian chaos squirrel god, Ratatoskr -- on in this insane conflict? Get ready to experience Squirrel Girl's first big event!"-- Provided by publisher.
