In 1849's famine-ravaged Ireland, thirteen-year-old Mary Boland is found lying mostly dead on the side of the road to Cork Harbor, Queenstown, Ireland. She just buried her mother and baby sister after they both died of starvation. Now she is headed for Boston to find her father-- no matter what. Raped and beaten by the evil crew of The Pilgrim's Dandy, she is rescued by a fifteen-year-old Negro slave who had been used in like manner for some time and had vowed to throw himself to the sharks that very night. Together they survive the harrowing two and a half month trip, helping others as well. Their friendship is the key to the new world for both of them, carrying them through hardships and trials, and eventually to happiness.
