Canada, 2018: At ninety-seven years old, Winnifred Ellis knows she doesn't have much time left. Soon she'll be gone, just like her husband, her daughter, and the many loved ones she's lost over the years, and the story of her shameful past will die with her. When her great grandson Jamie, the spitting image of her husband, asks about his family tree, Winnifred can't lie any longer, even if it means breaking a promise she made so long ago. England, 1936: Fifteen-year-old Winny has never known a real home. After running away from an abusive stepfather, she falls in with Mary and Jack and their ragtag group of friends roaming the streets of Liverpool, but when they are caught stealing food, Winny and Mary are placed in Dr. Barnardo's Barkingside Home for Girls, a local home for orphans and forgotten children found in the city's slums. There, Winny learns she will join other boys and girls in a faraway place called Canada, where families eagerly await them. But when they arrive, their dream of a better life is quickly shattered. Winny is separated from Mary and Jack and sent to live with a family who doesn't want another daughter, but an indentured servant to work on their farm. Faced with this harsh new reality, Winny clings to the hope that she will someday find her friends again.
