Envy drives the God of War into a realm of fire to reclaim his glory, in this epic fantasy novel of Odin's greatest heroes, in Marvel's Legends of Asgard. Tyr, God of War and older brother of Thor, embarks on a quest to regain his honor and place at Odin's side. He is urged on by the loyal young Bjorn Wolfbane and the enchanting Lorelai, and together the trio sets out to steal a piece of Twilight, the sword of the fire giant Surtur, who will one day cause Ragnarok and destroy Asgard. But the fiery realm of Muspelheim is littered with volcanic trolls, lava cracks, and Surtur's murderous warriors. Tyr must overcome his own feelings of inadequacy and the motives of his allies or risk causing the apocalypse and forever damning his name.
