Unable to resist temptation, she fell head over heels in love with the maddening man, despite discovering evidence that he was a traitor to his country.

Alex thought Lady Hartford's house party would prove an excellent cover for his dangerous mission. But an innocent scavenger hunt that threw him together with Chastity Hartford would sweep them into a dangerous adventure where spies threatened to take not only to their lives but their future - together.
