Never Disrespect a Governess (The Neverhartts #5)
Dawn Brower

Damon Neverhartt, the Earl of Seville is the youngest child and has been coddled his entire life. For the brief time, after his parents' death, when the family struggled he'd been kept in the dark. After his sister married the duke, he was sent to school. Now, he's home and ready to take over his family estate. His circumstances are not what they once were thanks to the duke's guidance.
While visiting Graystone, he has several encounters with their new governess. She's pretty, intelligent, and much too easy to tease. He lies about his identity when she believes him a servant. Something that he comes to regret later, when she uncovers the truth and decides he is a dishonorable gentleman. Damon has to work fast and hard to win her again, as Raeanna remains uncertain if he's trustworthy or merits a place in her life. He learns fast to never disrespect a governess, as he attempts to earn her love.
