Book excerpt: Collects War of the Realms Strikeforce: The Land of the Giants, The Dark Elf Realm and The War Avengers. Earth's heroes undertake a multi-pronged mission to win the War of the Realms! With Thor trapped in Jotunheim, Captain America takes up the God of Thunder's ax, Jarnbjorn, and leads a team including Spider-Man, Wolverine, Luke Cage and Iron Fist into the land of ice and snow in search of their fellow Avenger! Meanwhile, All-Mother Freyja leads the charge to shut down Malekith's Black Bifrost - and Hulk, Blade, Ghost Rider and Punisher follow her straight into the Dark Elf's home territory! And it's up to Captain Marvel and her War Avengers - Weapon H, Captain Britain, Venom, Deadpool, Winter Soldier and Black Widow - to reclaim the Earth! But Malekith's army is vast, and Carol is fighting a losing battle!
