Lust is a Sin . . . Sebastian Griffin, the Duke of Melbourne, has raised his younger siblings, seen to it that they made correct matches, and basically kept everyone in line. Seen as the most powerful man in England, Sebastian has a reputation for propriety and has maintained a scandal-free life. Until now. Josefina Katarina Embry is a beauty, to be sure, but she claims to be the princess of a faraway country. While she dazzles the ton with her wit and charm, Sebastian suspects she's up to something. And he's determined to expose her . . . if only he wasn't so distracted by her brazen sensuality and the irresistible allure of her kiss. Sebastian knows an affair will lead them into scandal, but will the most powerful man in England risk all for a princess of dubious lineage . . . or will he allow a most sinful desire to rule his heart?
