As the niece of an earl, Elizabeth Abbington knows all about the stifling expectations and responsibilities placed upon peers of the realm. She has no desire to marry into that kind of life. Instead she dreams of traveling abroad, where she can put her talent for languages to good use. When her dear friend invites her on a trip to Spain, Libby jumps at the chance to begin her adventure.

After his younger brother loses a small fortune on the turn of a card, Philip Dain, Duke of Gillingham, decides an intervention is in order. Determined to keep Nigel from falling into the lifestyle that ultimately destroyed their father, Philip offers a deal: If his brother can live in anonymity for a month with him in Spain, Philip will pay his debts outright. By stripping them of the privileged status they've always known and the negative influence of Nigel's friends, Philip hopes, the trip will help turn his brother around.

What Philip doesn't expect is how much he will relish the freedom of shedding his title, if only for a while. When his lack of understanding of the language becomes an issue, Libby comes to his aid. As she falls into the role of their informal interpreter, Libby sees the real him, which makes the growing attraction between them all the more heady. But as love blossoms under the Spanish sun, so, too, does his uncertainty of what will happen when she discovers she's been...Deceived by a Duke.
