What happens when you take a surly duke and a resourceful heiress, muddle them together in a convenient marriage, and add a hearty dash of Christmas cheer?

After coveting Helen's property for years, the Duke of Bellême proposes a 'mariage de convenance.' However, his independent new duchess has an alarming effect on his choice to avoid emotional entanglements.

Miss Helen Paxton, a clever young woman with an unusual legacy, needs to marry in order to save her birthright from her father. But protecting someone she loves—and guarding her heart—from her endearing grouch of a husband could be more than she can manage.

It might take all twelve days of holiday festivities, a kissing bough, and a winter storm to convince these guarded newlyweds that they already have the ingredients for the perfect, unexpected Christmas—one that will change their lives forever!

Helen of Castleford is a sweet, closed-door Regency Christmas romance. The events in this novel occur seven years before the start of The Dishonourable Paxton series.
