Ian von Leeuven finds his German grandmother's prayer book in a forgotten box in his mother's Virginia basement. Elsbet was a propagandist for the Third Reich and died late in the war. There are clues in the prayerbook pointing to something hidden in the attic of his grandmother's old home in Potsdam, Germany.

Devotees of Odin and Thor have found out about the artifact, stolen by Elsbet, that has languished for the past 70 years in her old attic. The religious order sends a man to search for and steal back Thor's Medallion. And they are prepared to do anything to retrieve the medallion, including kidnap and murder.
