My name is Magnus Chase. Two months ago I died fighting a fire giant and woke up in Hotel Valhalla as one of Odins warriors. Time for a rest? I wish. When I meet Otis, an informant with a lead on Thors missing hammer, all I get is the name Provincetown before a wolf-masked assassin takes him out and warns me to stay away. Someone really doesnt want me to find the hammer, and even if I could its rumoured to be underground, guarded by powerful magic. But the giant armes are on the move, preparing to invade. If I dont find it, theyll ravage the Nine Worlds, starting with the streets of Boston. Theres just one person who could help. Someone who demands a very high price: the gods worst enemy, Loki.--Back cover.
