Heart of Stone: A Dark Cowboy Romance (Wounded Hearts #3)
R. Collins

Dr. Kennedy was as normal as any professor I’d had before. Until he found out my secret. Friday night changed my life, and when I got home, I wished I was dead. Then I realized I wanted revenge. I found out quickly I was wrong about Dr. Kennedy. He’s just as screwed up as I am. Maybe more. Definitely more. I mean, the man agreed to kill my boyfriend, and he’s already planning on who to take out next. All I have to do in exchange is work on his farm and be his perfect little pet in his room that he used to share with his dead wife. His wife who he killed. This is my life now. A former student turned killer whose accomplice is her teacher. Her teacher who has promised to get rid of her enemies and keep her name clear. All I can hope is that I’m lucky enough to make it out of this alive.
