My only books were women's looks

When the handsome but notorious Lord Vidal attempts to make the gorgeous Sophie Challoner his mistress, he gets her down to earth no nonsense sister Mary instead, as Mary bids to save her sisters reputation. In doing so, she ruins her own, and so Vidal offers to marry her to save it...Hands down my favorite Heyer - I've read this one a few times. And I'm not alone - I was reading it on the train the other day and a woman tapped me on the shoulder and says, "I just wanted to say that you're reading my favorite book in the world." Vidal is the ultimate original bad boy - the book opens with his shooting and killing a highwayman who attempts to hold up his carriage, and calmly ordering to drive on. He gambles high, drinks to excess, seduces women left and right...yet he adores his mother and respects women (if they've respectable like Mary.) Heyer manages to take what may now be one of the biggest Romance cliches in the book - rake abducts heroine, who manages to reform him - into something so much more. Such a fun read!
