Lady of Desire (League of Rogues #1)

Miss Margery Derrington and her dear aunts are in dire straits. Their discovery of a rare manuscript will hopefully stave off their creditors-if it's worth what they hope. Margery reluctantly allies with a reclusive scholar to use the book to pursue a treasure that could solve their woes. Only, the irresistible desire she feels toward her partner is neither expected nor wanted. Rhys Bowen can't believe he has his hands on the elusive de Valery text. Solving its hidden code and unearthing its legendary treasure would establish him as one of Britain's leading antiquaries, finally casting him out of his brilliant late father's shadow. But when a centuries-old organization convinces Rhys of the perils of disturbing the past, he must choose between his conscience...and the captivating woman he's sworn to help.
