Aurora Huntley, free-spirited sister to the earl of Pembourne, lives under the dark shadow of the black diamond. The victim of threats from privateers who believe her brother possesses the precious stone, Aurora is a virtual prisoner in her own home. She now faces a fate worse than death: an arranged marriage to an uninspiring suitor. Craving adventure and freedom, Aurora has no choice but to do something shocking, something scandalous...

For two hundred pounds, a handsome stranger agrees to help Aurora stage her own ruin. But her kiss stuns him, and her name shocks him. She is a Huntley, and he is Julian Bencroft, the new duke of Morland. For generations their families have been bitter enemies because of the black diamond. Now, joining forces to claim the treasure, Julian and Aurora discover a love that is far more precious than any jewel. But first, they must conquer the evil that surrounds them-or surrender their newfound joy to the diamond's age-old legacy of betrayal.
