Desperate to avoid being married off to the first bidder, Greer Fairchild travels to Wales to obtain an advance on her inheritance from her uncle. But upon arrival, she learns her uncle died and a distant relative, Rhodrick Glendower, the Prince of Powys and the Earl of Radnor, now controls her inheritance. A man rumoured to have a dark past, the prince not only refuses to give Greer her inheritance, he locks her up in his castle. Although Greer is a prisoner, she is free to roam Rhodrick's castle, and she finds a portrait of her deceased mother. Until Greer can put all the pieces together, she must fight the dangerously strong attraction that's flared up between her and the rough and lonely prince.
