The Duke And I, Amanda Quick; Avon Books, Inc.

“By all accounts, Simon Basset is on the verge of proposing to his best friend’s sister, the lovely—and almost-on-the-shelf—Daphne Bridgerton. But the two of them know the truth—it’s all an elaborate plan to keep Simon free from marriage-minded society mothers. And as for Daphne, surely she will attract some worthy suitors now that it seems a duke has declared her desirable.

But as Daphne waltzes across ballroom after ballroom with Simon, it’s hard to remember that their courtship is a complete sham.”

Robin’s Note: The Bridgerton series, which starts with this title, is a fan-favorite for Regency romance fans, and Quinn’s novels ensnare readers who are not usually romance readers with their smart dialogue and insight into romance.  This series is known for both the quality and romance among the romance readers I know, and is considered one of the better Regency series.  Lisa Kleypas was another author mentioned, and she may also be a place to look for solid Regency titles.
