When Charlotte Wilmont, an awkward and all-too proper spinster, inherits an old ring, she hasn’t any idea of the power that she now wears on her finger. The ancient ring grants each bearer one wish, and unwittingly, Charlotte wishes that the man of her dreams, Sebastian Marlowe, Viscount Trent, loved her. The next morning she awakens to finds herself in a bed, naked, with none other than Sebastian. She’s gotten her wish, for she is the woman he loves, but there’s one small hitch, she’s his mistress. Adding to her shock, Charlotte finds that the world she once knew is all turned around and now she’s the most sought after courtesan in London. As she discovers her “Lottie” alter-ego, she also finds that Sebastian’s love can come at a high price. If she keeps her wish, she’ll ruin his chance to make a good marriage and save his family from financial ruin, but if she disavows it, she’ll lose the only man she’ll ever love.
