Can the power of Viking blood defy death? In 1907, Alison MacGiverson sees her body laying on the beach at Tiburon Island. Yet her spirit mysteriously merges with Asta Haroldsdottir, the young bride of Viking explorer, Eirik Sigmusson. Tied to Asta, Alison travels back in time from the shores of Tiburon to medieval Sudrland, assuming her role as spirit guide. Forced to relocate after the loss of their family farmstead in Iceland, Erik and his brother, Sigmus, sail to their mother's manor and swear fealty to the clan chieftain, unaware of the duplicity rooted in their adopted homeland. With danger imminent, can Alison's ghostly presence help or hinder the Sigmussons as they ferret out friend from foe, and suspicious spectre from meddling voyeur?
