Born into a family of wealth and power, Shannon has to reinvent herself when her father's business collapses. Planning to relocate to the home of her forbearers in Ireland after college, Shannon immerses herself in her studies. When an old book reveals a mysterious scrap of vellum with musical notes and her name, she finds herself whistling a different tune in a different time--a time of mists and warriors, Druids and legends, and a handsome Irish outcast named Lasairian.
