The Duke and I by Julia Quinn revolves around the fourth daughter, fourth letter of the alphabet is D, thus she is named Daphne. Being the oldest of the sisters, she is out for a husband, however, she is too friendly and intelligent to catch the love interest of the men of the ton. She's been in the market for two years, but no decent man had caught her heart. However, she meets Simon Basset, Duke of Hastings, which of course is irresistibly handsome and considered a great catch by all the mamas who are in search for a husband of their daughters. Daphne and Simon both find themselves in a need of each others assistance. They would pretend that they are besotted with one another to gain the following end results:

Firstly for Daphne Bridgerton, her mother will stop dragging her from man to man if she thinks that Daphne has secured the interest of Simon.

Secondly, Simon Basset's "make believe" attraction for her would attract attention of other males of the ton since Simon believed that men are always more interested in a woman if they think other men are interested. "But if all the world thinks I intend to make you my duchess, all of those men who see you as nothing more than a friend will see you in a new light," as Simon said to Daphne.

Thirdly, for Simon Basset, all the mamas, all the unmarried females and all the eldest sisters of the unmarried females of the ton, will finally put him at rest, since Simon has no plans to marry whatsoever.

All goals have achieved fruition.

However, even at the beginning, the two have accomplished unspeakable depths to fight the attraction they felt for each other. But, there comes a point where all the walls break and resistance comes tumbling, and all that is left to do is to embrace anything at reach, which was one another ♥
