Two time-travelling wise women from different centuries sail by Viking boat from 10th century Yorkshire to the ancient city of Byzantium to rescue 7-year old twins. Midwife and fledgling witch, Annie Thornton, and her cat Rosamund, reunite with Annie's Aunt Meg, a hereditary witch last encountered in 15th century Hallamby, England. Annie's sweetheart from the deep past reappears to help the women face the challenges of an arduous journey, made more difficult by a sinister Viking queen determined to get her way. Combining vivid historical detail with the imaginative possibilities of magic realism, Sailing to Byzantium is a spellbinding journey through time and cultures seen through the astonished eyes of a contemporary woman who both loses and finds her inner power.
