Say Yes to the Duke by Eloisa James

Viola Astley knows she's not a real Wilde. Her mother married into the family when she was two. Though the Duke and all of her siblings have accepted that she's a true "Wilde Childe," Viola has worked herself into such a thought pattern that she is physically ill before balls, even before just meeting eligible men. She isn't a Wilde by blood and, shorter than the rest, plumper than the rest, she doesn't even look like she belongs. But then she meets the new local vicar and falls in love. Too bad he already has a fiancee. And really too bad that a duke seems to have set his eyes on her.
Devin Lucas Augustus Elstan, Duke of Wynter, is ready to get married. He might as well marry a Wilde, but not the adopted daughter. Instead, he'll check out the one who is generally known to not be a Wilde by blood but is by name. Even his uncle pushing him to meet Miss Astley doesn't make him interested in Viola. But when she stands up to him, well, that catches his notice.
This is a fairly quiet book. Not a lot of conflict and that was just lovely right now. Even the last misunderstanding wasn't a Big Misunderstanding because they actually talked to each other.
