The Turning — Pauline Holdstock

In 1870, while France and Prussia are at war, an English ship is wrecked on the coast of France and a stranger enters the lives of a village family. Elisa Gagnon is married to the man bent on salvaging the wrecked Lady Morgan at any cost; her daughter Janik sees angels, but her father would rather see her married than enter the convent; Alan Bridges arrives among them with an unknown past and suspicious intentions. When a ruinous triangle develops between these three, they are forced to choose between their allegiances -- emotional, spiritual, and political -- and their desires.
