The villagers think her one of the fairy-folk, for she was found wandering the Highlands at the age of four, able to communicate with the creatures of the moors. Now eighteen, Sarah quietly uses her gift to heal wounded animals. But when word of the lovely changeling spreads, her peaceful existence is shattered.

Convinced Sarah is his long-lost daughter, the powerful Duke of Argyll offers to bequeath her his estate if she will but take her place in society. Her first duty is to become a lady-under the tutelage of the duke's erstwhile heir, the dangerously provocative Earl of Cawdor. Sarah savors the simmering passions the cynical earl arouses in her even as she suspects he is merely using seduction to secure his birthright. In this civilized world where desire and deception are one and the same, how can she ever trust in love?
