A World of Magic and Peril 1899, Sand Island, Wisconsin: Bridget Lederle is a lighthouse keeper on this stormy, windswept shore of Lake Superior. One cold night she sees a boat foundering near the islands shoals, and rescues its lone occupant. The strangely dressed sailor tells her a fantastic tale, of Isavalta, a world where magic reigns, and where she is-incredibly-destined to play a key role in a power struggle between the Dowager Empress and her foes. Isavalta, where magic can be found in the pattern of knots on a string, the colors of a dress, or even smoke in the air, beckons to her. Bridget has the second sight of her family, but the magical land where she will go with the sailor holds far greater marvels, and terrible perils that even she cannot see. For she carries secrets within her that even she doesnt know, secrets that could change the fate of the fabulous magical world that calls her home . . .
