Secrets of an Accidental Duchess (Donovan Sisters #2)
Jennifer Haymore

It was a reckless wager, and one Max couldn't resist: seduce the alluring Olivia or forfeit part of his fortune. Yet the wild, soon-to-be Duke never imagined he'd fall in love with this innocent beauty. Nor could he have guessed that a dangerously unpredictable rival would set out to destroy them both. Now, Max must beat a Madman at his own twisted game-or forever lose the only woman to have ever won his heart.
