Snowed by the Wallflower. Revenge of the Wallflowers, Book 48 of 55

Belinda Westcott doesn't want to injure the Earl of Ridgemont. She merely wants to humiliate him. After all, one good prank deserves a payback. How could she anticipate that it would go so terribly wrong, or that he would turn out to be nothing like she expected? Skilled in both chemistry and cooking, Belinda happily hides in her aunt's kitchen rather than risk embarrassment at the ongoing house party.
The unexpected appearance of the earl and a skating party present the perfect opportunity to embarrass him in front of some snooty society miss. Unfortunately, his partner is Belinda's own cousin, and even worse, the cousin drinks the hot chocolate-laced with emitics-meant for the earl. As plain Major John Conlyn, John had sunk into a morass of dissipation when first released from the army. Neither his actions nor his companions make him proud.
The death of a beloved cousin shocked him back to sense. It also made him an earl and the heir to his grandfather, a duke. He's been ordered to find a wife and settle down. He wouldn't mind, but now he's surrounded by flighty debutantes and their grasping mothers. The one woman who interests him avoids him. She acts as if she despises him. Is it possible he did something when out of control that he ought to apologize for, something he can't recall?
