WAR OF THE REALMS TIE-IN! You know how Squirrel Girl has stayed out of most Marvel events? Turns out, that was only because THOSE events didn't involve her good pal LOKI LAUFEYSON! When Earth is attacked as part of the WAR OF THE REALMS, Squirrel Girl is called back from her Negative Zone vacation, and Loki recruits her as part of a secret mission! Is Loki running a scheme? Probably. Is he playing a trick? Almost certainly. But he NEVER lies about the safety of his good friend (and Cat Thor creator) Nancy Whitehead, and that puts him and Doreen on the same side. It's Squirrel Girl's first BIG EVENT CROSSOVER... but it's still the start of a stand-alone epic that you can still enjoy even if you only read SQUIRREL GIRL! Also if you're reading this because you're thinking, ""Hmm I'm big into WAR OF THE REALMS but do I really need to see what happens in SQUIRREL GIRL"" then let me say WOW DO YOU EVER, THERE'S A REVEAL ON THIS LAST PAGE THAT'S BEEN IN THE WORKS FOR YEARS!
