Full review at Smart Bitches, Trashy Books 
 I have been waiting for this book for SO LONG and it was worth it. Every time Hoyt released a book in the Maiden Lane series I would gobble it up and then whine on Twitter "But when is Val's book coming?" Well, it's here now and it's 100% what I was hoping for. 
 Duke of Sin by Elizabeth Hoyt is one of those books that worked for me on all levels, but I can see where it would problematic for some readers. First of all, it's pretty damn dark. Secondly the hero, Valentine Napier, Duke of Montgomery is going to be one of those heroes that readers either love or hate. And I loved him. God, I loved him. 
 If you've read the other Maiden Lane novels (and I strongly suggest you do) then you know that Val, if not an outright villain (and that's an arguable point), is at the very least an antagonist. He's a master manipulator, a blackmailer, a man playing chess with human lives. His actions have moved along the plots of previous novels. He's vain. He's debauched. He's ridiculously handsome. He's erudite. He's wicked. He's at least a little bit insane. 
 Like I said, Duke of Sin will either be a love or a hate with a lot of readers. Val is never totally, completely redeemed. He's not outright villainous at the end, but he's definitely not transformed into prince charming. His actions in this book certainly have the potential to be polarizing. I was willing to forgive Val because I knew what I was getting into. He represents a serious bad-boy fantasy. When I put the book down I felt like Val had grown as a person, but that he was absolutely still capable of violence and deceit. 
 If you love a hero with an ulterior motive, a man who is capable of doing dark and monstrous things to achieve his version of justice, then you're going to love Duke of Sin.
