After her aunt's death, Métis woman Brigitte Marchal finds herself alone in Montreal. Uninterested in the convent and desperate to flee a loathsome suitor, she disguises herself as a young man to travel west by voyageurs' brigade in search of her long-absent, fur-trader father. But her inexperience and disguise don't hide her for long. René Dufour yields to the unwelcome position of shielding Brigitte, but he cannot hide her identity forever. Keeping her safe while meeting his North West Company obligations and honoring his family promises may prove to be more disquieting to his heart than he imagined. As Brigitte adjusts to the voyageur life on Lake Superior, she struggles to justify the faith she grew up in with the mysticism around her, but greater still is the conflict her heart must settle over who to trust in this rugged, unfamiliar country.
