Trapped in the extravagance and the artifice of the French court during the reign of the Sun King, Louis the XIV, Madeleine becomes desperate for an escape. When the king himself offers her the opportunity to flee to the New World, Madeleine eagerly accepts.

Madeleine soon embarks on a new life in Ontario, but the trials of her past are not so easily left behind. Life on the frontier is fraught with its own opportunities and danger. Madeleine explores roles such as teacher to the Hurons, lady voyageur, and proprietor of a fur-trading post on Lake Ontario. Yet when the Iroquois attack her homestead and take her captive, her life and spiritual faith change forever. Based on the actual life of Madeleine de Roybon D’Allone (1646–1718), White Heart is a compelling story of faith, love, and recovery.
