A Rose in Winter

These two love each other and are torn a part when her father insists she marry another for his lands. Turns out he's an evil abusive bastard but no one knows until nine years later when he goes to France to inform her of her father's death and she coerces him to flee with her back to England. It's a lovely romance with love winning out.
