My Own True Duchess (True Gentlemen)

Jonathan Tresham, heir to the Quimbey ducal title, needs a discreet ally to help him choose a wife from among the army of young ladies eager to become his duchess. Proper widow Theodosia Haviland rescues him from a compromising situation, and he knows he's found an advisor he can trust. When Jonathan decides that Theo's name should be the only one on his list of possible duchesses, she protests, though she knows he is kind and honorable beneath his gruff exterior. Theo is guarding secrets, and a ducal heir is the last man she can marry, even if she does harbor a wholly inconvenient attraction to him.
