The goddess Freyja raises former King Eirick from the dead. The god Frey encourages Eirick to seek the Horn of Helheim, since only the undead can venture there and return.
Eirick gathers a ship and two close allies (Brynna and Sven) on the way to a nearby kingdom where the king remembers and likes him. He gathers more allies and sets off to find the druid Alcuin, who shows him the way to Helheim.
Eirick obtains the Horn with the help of the shade of his father, who informs him that his real father was someone else. Great stuff. Eirick and company proceed to Eirick's former kingdom, where his younger brother now rules. They are betrayed, but still manage to get to the meeting with Thor before the time of the 'Blood Eclipse' of the sun, which occurs once every 800 years.
Thor has the Hammer of the Gods (Mjolnir) from Valhalla, the Horn Eirick liberated from Helheim, and the 'Necklace of Mary Magdalene' from Midgard. The stakes are supposedly rather high at this event. In any case, secrets are revealed, and a climactic battle ensues.
The ending begs for a sequel.
