Bianca Blythe: The Duke Trap

Determined Debutantes, Volume 3
One determined debutante. One despised duke. One brilliant plan.
Leonora Holt never expected that her two younger sisters would find love before her. Lately she's grown disconcertingly accustomed to her brother's sighs and hints that she needs to marry. How can she find anyone when one dreadful man, the Duke of Dartmouth, is intent on reminding all the ton of her mother's scandal?
Sebastian, the Duke of Dartmouth, knows he should probably forget how the Holt family destroyed the last years of his father's life. At one point, he even considered Leonora Holt his best friend. Of course, that had been when he was ten, and he's achieved far more wisdom since then. He's also gained a secret, but that's something he has no intention of ever revealing.
Leonora is determined to trap Sebastian. If his reputation is maligned, perhaps he will halt disparaging her family.
Fortunately, she has the perfect plan, one that absolutely does not involve falling in love with the duke herself.
