After she is caught behaving obscenely with another woman, Sophia is left abandoned. Her friends pretend not to know her, her family is trying to decide the best place to banish her, and Sophia wishes that running away was as easy in fact as it was in theory.

She is saved from scandal, if not her suffocating life, by way of an unexpected marriage proposal from Lord Everett Dobson, the most coveted bachelor in the city. Not in a position to refuse, Sophia accepts his offer and agrees to visit his home at Mermaid Cove for three weeks.

Mermaid Cove proves to be as beautiful as promised, complete with endless beaches, glittering waters, a castle that looks like it was made of sand... family curses and local legends... and two beautiful, mysterious women who cannot talk, but seem to have secrets they want to share...
