My name is Magnus Chase.
Two months ago I died fighting a fire giant and woke up in hotel Valhalla as one of Odin's warriors.
Time for a rest? I wish.

When I meet Otis, an informant with a lead on Thor's missing hammer, all I get is the name "Provincetown" before a wolf-masked assasin takes him out and warns me to stay away.

Someone really doesn't want me to find the hammer, and even if I could it's rumoured to be underground, guarded by powerful magic.

But the giant armies are on the move, preparing to invade. If I don't fint it, they'll ravage the Nine Worlds, starting with the street of Boston.

There's just one person who could help. Someone who demands a very high price: the gods' worst enemy, Loki.
