An Adventurous Lady — Valerie King

WITH A LITTLE LUCK...
Possessed of an ancient map that marks a smuggler's buried treasure, Lady Evelina Wesley has only to secure the cooperation of her neighbor, the Earl of Rotherstone, to find it--but he flatly refuses to permit her onto his property! Piqued at his obstinacy, she tries sweet persuasion and Lord Rotherstone agrees at last, though at a price. When asked, she must relinquish three things of inestimable value to her. How is she to know that she will lose her heart as well?

...AND ALL HIS LOVE
Rotherstone is certain that Lady Evelina and her eccentric party are seeking a treasure that does not exist. But he is drawn to the fiery, red-haired beauty, despite his misgivings. As the madcap hunt begins, his carefully protected world is turned upside down--and Lady Evelina's spirited charm proves irresistible...

Hero: Lord Gage Rotherstone
Heroine: Lady Evelina Wesley
