Never Deny a Duke in Christmas by Harriet Caves

She’s fallen. And the duke, for entirely pragmatic reasons, would catch her.

Ruined and humiliated by her own husband, Kendra is now a fallen woman. But attend the Christmas festivities of the Ton she must. Even if she has to go through hell just for the sake of her father.
Nothing stings more than unrequited love and Ducnan Matthews, the Duke of Reedson, learned this the hard way. And despite living in sin for the past years, his heart still betrays him at the sight of the very woman who broke it.
Threatened with financial ruination, Duncan desperately needs a wealthy wife and Kendra needs a savior. With their own futures at stake, it’s finally time to confront the past, to trust in each other, and against the odds, find the love they lost—if she will only say yes.
