The Bastard's Bargain by Katee Robert

Oh! My! Gosh! This was the best book of the series, and that's saying a lot since this series completely owns me! Dmitri, Wow, just wow! He was so unbelievably sexy, and so completely unaware that he was halfway in love with Kiera before he ever convinced her to choose him. He wasn't a good guy at all, but he certainly treated Keira like his queen. He was every bit her "gentleman murderer" ( so loved that nickname, by the way). This story was crazy hot, super intense, and far exceeded my already high expectations. I'm so sad there are no more O'Malleys left!
