A Kiss at Mistletoe by Tamara Gill

Lady Mary Dalton fills her time with anything she pleases–and she pleases to do as she likes. With no interest in a husband, Lady Mary is perfectly content to remain in Derbyshire for the rest of her days. However, Mary’s parents have other ideas.
For the Christmas festivities at Bran Manor, Mary’s brother brings home the Duke of Carlton, an infamous man known for his many improprieties, as well as for his distaste in matrimony. Despite his rakish ways, Mary is drawn to him in the most vexing and exasperating way.
But when Mary stumbles into the Duke of Carlton’s arms one snowy eve, an undeniable attraction is set into motion. Suddenly, marriage no longer seems so horrific–for either of them.
