When a mysterious note arrives from Tristan Bonnaud asserting that the Duke's brother is alive, it leads Max straight to the winsome Lisette Bonnaud, illegitimate daughter of a viscount and Tristan's sister. Soon he and Lisette are traveling to Paris posing as husband and wife, in search of Tristan, who has disappeared. And the longer he spends with Lisette, the easier it is for Max to see that the line between dukedom and desire is easier to cross than he imagined...

    But when her brother's love match is thwarted by the impossibly proper Duke of Kerstone, Miranda sets off to convince the duke to champion her brother's cause for love. Unfortunately, he is too proper to consider love a suitable reason for marriage, and too proper not to marry Miranda when they find themselves compromised. Now, Miranda has a second chance for happily-ever-after, if she can uncover her new husband's darkest secret.
