A Scoundrel’s Promise by Tarah Scott

Lady Mackenzie has given much thought to falling in love, but didn’t plan on falling in love with a Beast of Blackstone Abbey. She fell from her horse and he saved her. True, he is a scoundrel, but even scoundrels can fall in love.
Lord Liam Fraser has seen enough war to last a lifetime. He plans to stand by his brother’s side and work the land of Blackstone Abbey. A lady’s company is welcome on a cold Highland night. But marriage? Nae—especially not to a spoiled earl’s daughter. No matter how willing—or beautiful—she might be. If she insists, he will have to prove that scoundrels don’t fall in love.
