Joy to the Earl by Nicola Davidson

Shunned for his mismatched eyes and awkward limp, Yorkshire carpenter Jack Reynolds lives a lonely and impoverished existence. Then comes a shocking discovery: he’s the discarded heir of a wealthy noble family, and if he travels to London by Christmas, he’ll not only gain an earldom, a home, and position like he’s never dreamed, but maybe—just maybe—he can finally lose his damned virginity.

Scandalous widow Rosalind Nelson’s life centers around four things—her young daughter, helping couples suffering sexual discord, avoiding all peers, and definitely not falling in love. That is, until the day she rescues a mysterious stranger from a carriage accident. Kind, brave, and achingly seductive, Jack is everything she’s ever wanted. Nothing can destroy their growing bond…except the demons of his past…
