"In this thrilling historical adventure set during World War II, Steve Rogers (AKA Captain America) and his young sidekick, Bucky Barnes, encounter threat like none they've ever seen -- a Ghost Army. The dead of this war and wars past are coming back to life, impervious to bullets, flames, or anything else the Allies can throw at them. The armies rise from the ground in the night and seem to disappear without a trace. How can Cap and Buck fight something...

The Avengers have defeated Loki and Norman Osoborn, but Asgard lies in ruins. As Captain America and Iron Man argue and Thor laments the loss of his father's legacy, the three are thrown by unstable Asgardian magic into the Nine Realms, where, lost and separated, they realize for the first time just how wrong things have gone, especially with Hela, the Norse Goddess of Death, prepared to step into the void left Asgard's fall has created.
