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.

Tragedy brought them together. Now truth might tear them apart. Wed to a trading company partner to escape life in Montreal under her harsh father's thumb, Camilla Bonnet finds herself widowed and pregnant in the Upper Country frontier. When her brother fails to return for her from Fort William, she is cast on the mercy of the trading post owner's family. She also draws comfort from Bemidii Marchal, a Métis hunter who soothes away her misgivings as he finds his own refuge on Lake Superior's Madeline Island. Bemidii’s thoughts of courting a maiden are cut short when he raises his knife against a company man at Fort William’s Great Rendezvous. No one will believe he killed to protect his sister—least of all the beautiful Frenchwoman on Madeline Island who stirs his affections—not when she learns that her brother is dead and Bemidii stands accused of his murder. As the sharp blade of truth divides them, will Bemidii survive the justice of powerful men who are a law unto themselves?
