Jason Aaron's Asgardian epic concludes with the final fate of the Mighty Thor, the return of the Odinson and the cataclysmic War of the Realms! But before Jane Foster lays down Mjolnir, she will join the League of Realms, lead Asgard against the Shi'ar and face the vengeful War Thor! But when final judgment arrives in the form of the monstrous Mangog, will Jane make the ultimate sacrifice? And as the realms fall before Malekith one by one, can Thor prove himself worthy once more? When the war reaches Midgard, everything will change for the God of Thunder!
