Shadows on the Rock is a historical novel set in Quebec in the late seventeenth century. It centres on Cécile, the young daughter of an apothecary, who keeps house with care and devotion while her family tries to maintain French customs in a distant colony. Through her daily life and the people around her, including a bishop, a governor and local children, the book builds a quiet picture of a small community clinging to tradition at the edge of a vast continent. It is a gentle novel about home, habit and continuity.
