Enslaving the Day — Jenn Langston

One night's mistake finds Lady Annalise Hera in a very compromising situation. Pregnant, unmarried, and on her way to Gretna Green. Although Baron Dailey put her in this position, she belatedly realizes she can't marry him and will do anything to get him to release her. Even lie. After all, life would be better as a disgraced, unwed mother than the wife of a cocky, irritating man she can barely tolerate.

Gordon Ashford, Baron Dailey, never thought much about his friend's younger sister. That was, until she grew into a beautiful woman. Now, after one drunken night when he took her innocence, he can't seem to get her out of his head. With her constant refusal of him, and perpetual need to argue, he should give her up. But he can't, even though she's told him she's not carrying his child.

Convincing her to accept him proves to be near impossible, but he's not one to easily give up.
