Lucan Sullivan is a sociologist who's come up with a set of rules that, in his opinion, will guarantee a happy marriage. Unfortunately, April Morgan, his editor, sees things quite differently.
April considers Sullivan's rules biased, out of touch and out of date. In her opinion, Sullivan has no idea how real men & women think, act or feel. So April sets out to show him...and in the process discovers there's another side to Lucas Sullivan.
This other Lucas is a man who doesn't always follow his own rules. A man who's a quick learner, too - April Morgan's doing the teaching.
