A woman nearly faints at a ball, and when an earl tries to help her, her family manages to make it look like a scandalous liaison. They marry to avoid scandal, but neither is happy. Some stuff happens (I've already forgotten, only a few days after reading this) and they learn to appreciate and even love each other. The earl spends a ridiculously large part of the novel thinking she tricked him into marriage, even long after there's no reason to think that. He comes across as obstinately trying to believe the worst of her, which is not really what I look for in a romance.
