Major Elijah Hollister never wanted to be an earl, particularly not when it meant losing his brother. When a bold adventuress shows up at his door seeking a treasure map, Elijah suspects his brother's death may not have been accidental and that the lady knows more than she's willing to share. Whether she's a friend or foe, Elijah plans to keep her close-and hope the temptation of her kisses doesn't ruin them both. Miss Catriona Bowen can almost taste the fruits of her years-long quest to find one of Britain's greatest treasures. The discovery will deliver the recognition and respect she deserves as an antiquary, despite the fact that she's a woman. However, to find the map that will lead her to success, she must ally herself with a stoic, yet provocative earl with a different goal. And when a villain threatens their lives, she realizes too late that love is the greatest treasure of all.
