Forbidden

Daisy and the Duc de Vec are strong-willed and passionate and when first introduced at a Parisian ball, they dislike each other on sight. Daisy, Hazard Black's daughter by a lover, is one of only fifty female attorneys in the United States and the only Native American attorney of either gender. She's a beautiful, no-nonsense woman, very much her father's daughter; she doesn't tolerate fools.
No-one would characterize Etienne Martel, Duc de Vec, and bearer of a dozen lesser titles, as foolish. A shrewd businessman, world traveler, sportsman, polo player, connoisseur of art and women, he's also the most notorious rake in Paris; the primary reason Daisy considers him unacceptable.
But over a drink at his club later that evening, the duc finds his thoughts returning to the brief, acerbic exchange with Daisy Black, and he becomes increasing intrigued by the exotic beauty from Montana. What would it be like to bring the cool Mademoiselle Black to bed? A challenge. A fascinating challenge...
That the Duc de Vec is married turns out to be the biggest challenge of all.
