Forever My Duke by Olivia Drake

Hadrian Ames, the Duke of Clayton, needs a bride. He even has the perfect one picked out. That is, until he meets the lovely, free-spirited Natalie Fanshawe. She’s the opposite of what a man of his high rank should desire in a wife—an outspoken American who has never even set foot in a London ballroom.
But Natalie doesn’t have time to be swept off her feet by a handsome duke who must be a spoiled scoundrel like every other British lord. And she couldn’t care less about Hadrian’s title. After all, it’s not as if he actually worked to attain his wealth and status. He surely can’t understand what it’s like to be a busy woman, planning to open a school while trying to reunite a six-year-old orphan with his English relatives. Nevertheless, Hadrian launches his campaign to win her heart. Can the utterly delightful American beauty ever find a way to love him…despite his being a duke?
