The Tiger's Mistress — Andrea DaRif

When her beloved father mysteriously disappears, Portia Hadley is determined to discover why...even if it means charging straight into the arms of the Earl of Branford. Known as the "Black Cat" when he was a spy for England, Branford is no stranger to secret missions or mysterious ladies. Branford senses that Portia is not as innocent as her jade-green eyes suggest and a game of cat and mouse begins. Little does Portia know that Branford has his own secret agenda -- one that could ignite a sparking passion...and a deadly danger.
