To Enchant a Lady’s Heart by Robin Lee Hatcher

He has nothing to offer. She has everything to lose.

Despite the dishonorable circumstances of his own birth, Adam Faulkner has never begrudged his half-brother Sebastian’s legitimate position as the Viscount Willowthorpe. Having a title and everything that goes with it never mattered to Adam—until “everything” became the hand of Miss Eliza Southwick. Adam knows, as the stable manager at Hooke Manor, he shouldn’t hope to wed a well-born miss. After all, enchanting such a lady’s heart would take a true gentleman…something he is not.
Eliza Southwick loves horses more than society and doesn’t care a whit about status or titles. But her father has set his sights on the Viscount Willowthorpe for his future son-in-law and has brought his daughter to Hooke Manor in hopes of arranging a marriage contract. When a spark first kindled during a chance meeting between Eliza and Adam grows stronger, she doesn’t dare tell her father how she feels. He will disown her entirely if she fails to do his will, and the cost of following her heart has never seemed higher.
