Professor by Day, Master by Night

Lucy, a medical student worn down by abuse at home, finds her only refuge in a secret dominant-submissive bond with a mysterious man she calls Daddy. Her double life begins to unravel when Ethan Walton, a strict new anatomy professor whose voice matches Daddy's, walks into her lecture hall. When her gambling-addicted father tries to sell her to the mafia to pay his debts, Ethan rescues her at gunpoint and offers her shelter. Torn between her feelings for the professor and her loyalty to Daddy, Lucy is drawn into a dangerous tangle of secrets.
