Along Came a Lady by Christi Caldwell

The brooding, illegitimate son of a duke meets his match in the determined woman hired to transform him into a gentleman from USA Today bestselling author Christi Caldwell—perfect for fans of Bridgerton.

Rafe Audley lives to thwart his father, the Duke of Bentley. The ne’er do well who abandoned his children claims he wants to make up for his failures, but Rafe only cares about protecting the people of his mining community and providing for his three siblings, who’ve been his sole responsibility since childhood. So far, Rafe has turned away the duke’s man of affairs, solicitor, and other interlopers, until the clever duke sends the unlikeliest of people to convince Rafe to join English High Society—a bold and intriguing woman.

Edwina Dalrymple has never failed a charge. She’s quite adept at successfully transforming young women of the gentry and daughters of newly minted lords to take their place in society. Taming a bastard son of a duke will be child’s play, plus this job promises to enhance her reputation within the ton. All she has to do is fetch the wayward Rafe and groom him to be presentable to Polite Society.

As the tenacious teacher and her domineering, stubborn, refuses-to-be-taught pupil engage in a fiery battle of wills, their chemistry ignites and the true lesson becomes clear: opposites attract and hearts must be heard.
