Never Kiss an Earl at Midnight by Tammy Andresen

A bluestocking and a rake…
Lady Victoria Ducat has an orderly life filled with academic pursuits and the care of her ailing father. She has no use for a drunken rake like the Earl of Kissinger. Just because he is handsome, charming, and he makes her knees weak doesn’t mean she’s going to give up her principles. So what if Lord Kissinger looks at her the way no man has before? She’ll just ignore the heat in his gaze and the breathless want it brings. She had a plan and she’ll stick to it, which is a far sight better than getting her heart broken…isn’t it?
Kenneth Kissinger, known to his friends as Key, is happy living his life outside of polite society, drinking and gaming to his heart’s content. He has no use for debutantes and even less for a bluestocking and a wallflower like Lady Victoria. Except those plump lips call to him. Without a word, they promise sinful delights. Her actions speak as well, as she puts the needs of everyone in her family before her own. What would it be like to have the love of a woman like that?
But as fate, a bet, and family drama toss them together temptation becomes more difficult to deny. Can they resist temptation or will they share the kiss that has been foretold?
