Ragnarok came and went. The gods won. The giants retreated to recover from their wounds. But even in victory, the gods are uneasy. Hammerless, Thor quit Asgard in disgust. A half-machine Tyr interprets the babblings of a sightless Odin and Loki is imprisoned, both jester and reminder of the gods' costly victory. There is a rot at the center of the world, at the heart of the world-tree Yggdrassil itself. But only Thor will acknowledge it. Chasing the source of that corruption, astride his twin-engined motorcycle, Thor retuns to Asgard after his hundred year exile. Part magic and part technology amok, RAGNAROK SUMMER here is a maniac journey through the transformed worlds of the norse gods: to the stomach of the Midgard serpent, to glittering spires of Asgard City, to the frozen wastes of Niflheim and ravening infernos of Muspellheim, and to Hel itself where Thor and Loki pursue the secret of a failed apocalypse.
