Showing Black Sheep's Daughter by Carola Dunn

Teresa Danville, raised in Costa Rica by her “black sheep” father, presents a challenge to the diplomatic skills of Sir Andrew Graylin. Niece of an English duke, Teresa was not raised to London society, but to wielding pistols and overseeing a coffee plantation household. Bringing this exotic beauty (along with her brother and her parrot) to civilization gets the previously affianced Sir Andrew in deep trouble.
