Hannah's Duke: Regency Sexy Romance (The heir and a spare #4)

Hannah Castle is an American lady, sent back to London by her father, to find a decent husband. Her father's distant cousin was the Duke of Arrow, so when Hannah searches for a place within the ton, she lives with Lady Charlotte, her second cousin and the new Countess of Tother.

At Charlotte's summer house, she meets Lord John Dunford, a famous rakehell and rather handsome gentleman. He is lust and temptation encarnate.
Hannah had always promised herself she would wait until marriage, but would learning the arts of the bedroom be such a bad thing?

Lord John swore off marriage as a child. His fathers terrible union, and the devastation his mother expressed knowing his father was in love with his mistress, put him off love and commitment. But when he meets Hannah Castle, his once cold heart trembled at the sight. Even though he couldn't offer her forever, a few nights in his bed could be the solution to the attraction burning between them.
