In the treacherous court of 16th-century France, noblewoman Marguerite de la Rocque is a woman of dangerous independence. When her illicit affair with a young officer is discovered, her powerful and pious kinsman, Jean-François de Roberval, enacts a merciless punishment. She is marooned on the dreaded Isle of Demons, a godforsaken rock in the Canadian wilderness, and left for dead. But Roberval underestimated the woman he sought to erase. Stripped of everything, Marguerite endures a brutal ordeal of starvation, loss, and solitude that transforms her from a lady into a legend. Forging a new life from the raw materials of survival, she becomes a master of the wild, a huntress who conquers the island’s most terrifying predator. Her eventual rescue is not an end to her story, but the beginning of a new, more complex war—a psychological thriller fought not for survival, but for the truth against a world that has already turned her life into a lie.
