Matt Fraction's complete saga of Thor -- from triumphs and tragedies of ages past, to a bold new heroic era! Asgard is the target of a dark, destructive force from another reality -- and it's on the warpath! When Thor and Sif dive deep into the heart of the fractured World Tree, what they find attracts the attention of the Silver Surfer...and in his wake follows Galactus! But the most horrifying threat of all is the Serpent -- who will make the Son of Odin, and the whole Marvel Universe, know fear! Thor is fated to die...but can a team-up with young Loki stave off disaster, or will everything burn?
