Grace serves as the novel’s dynamic and round protagonist, whose life is explored nonlinearly across three distinct phases: “Maiden,” “Mother,” and “Matriarch.” Her evolution from a defiant girl into a formidable chieftain and stateswoman is central to the narrative. As a “Maiden,” Grace’s defining trait is her tenacious spirit and innate connection to the sea. She rejects prescribed gender roles from a young age, cutting her hair so that it “won’t get caught in the ropes” and she can join her father’s crew (1). This act symbolizes her lifelong refusal to be confined. Her choice of a compass over other items during a trip to Galway further establishes her destiny as a navigator of her own path. In this timeline, her relationships are formative; her father, Eóin, both nurtures and attempts to restrain her wildness, while her burgeoning connection with Richard Bourke shows a future of equal partnership that is ultimately denied to her, establishing a core conflict between personal desire and dynastic duty.

In the “Mother” timeline, Grace’s spirit is tested by the constraints of her arranged marriage and the domestic sphere of a castle. This period depicts her as resilient and strategic, learning to wield power within a patriarchal system by managing estates, settling rents, and earning the loyalty of her husband’s followers.
