Ten Rules for Marrying a Duke by Michelle McLean

Bromley never gave a fig for society’s rules—until her sister ran off with a man below her station. Now Arabella is desperate to restore her family’s ruined reputation to favor amongst the ton. She’ll have to marry quickly and well. But in order to carry off her plan, Arabella needs a duke… and she has just the rakish fellow in mind.

The Duke of Whittsley has an ungentlemanly tendency to disregard the rules. Unfortunately, a sense of mischief doesn’t excuse a high-ranking noble from family duty—especially where it concerns producing a son. And that’s where he can’t quite resist Arabella’s distinctly outrageous plan: if he saves her family, she’ll give him an heir.

Now the deal’s been struck. They have one year to achieve their goals and ten iron-clad rules to keep them on track. Like long, scorching kisses and ensuring they’re both exquisitely satisfied. And the only thing that could ruin their plan is the one thing they never planned on: love.
