At White's Club in London, two rivals dominate the whispered gossip and gaming tables - The Old Devil, the sinister Duke of Accrington, and The Young Devil, the cold, cynical Marquis of Thane. Their hatred runs deep, rooted in the Duke's merciless betrayal of the Marquis's dying father.

When he uncovers the stunning truth about her identity, he sees the perfect instrument for his long-awaited revenge.

But Fortuna is far more than a weapon. Her warmth, courage and charm begin to break through the Marquis's hardened heart, awakening feelings he never meant to have. And when she is abducted, his desperate rescue forces him to face a question - can he really use her for his ruthless revenge, or will love prove to be the most dangerous gamble of all?
