In an alternate world where magic works, the Holy Roman Empire still rules Europe, the time of the Renaissance has come, with very different results. Norway is still pagan, and a sacred relic, the Armring of Telemark, has been stolen from Odin's temple. Without it, truce-oaths cannot be renewed and bloody war with the Empire will follow. Signy, the older stepsister to the King Vortenbras is accused. When she disappears, most think it proof of her gult. Her only partisan, the Corsair-Captain Cair, knows that she had been carried off and is determined to find and rescue her. Cair is an educated man, and a hardened skeptic, thinking that all talk of magic is nonsense. As he and Prince Manfred of Brittany set out to rescue Signy, following her trail into the Underworld, battling trolls and other deadly supernatural creatures every step of the way, he will not only find that magic is very real, and dangerously so, but that he himself has a natural talent for it.
