Ten-year-old Ginny Morris, whose parents are divorced, lives with each parent a week at a time. One day when she arrives at her dad's after a week with her mother, she discovers that the house is spotless, the yard is spruced up, and even her own room has been messed with. The reason is: Dad has a friend named Ruth.

Ginny Morris's parents are divorced, which is bad enough, but now her dad has a girlfriend! Who is this strange man who's become a clean freak and smiles all the time? Will her dad still be the same? Does this ruin any chance her parents will get back together? Does her mom care? Is it okay if Ginny likes his girlfriend? Ginny sorts through her feelings with the help of her best friend, her journal--and some heart-to-heart talks with Mom and Dad themselves. This is volume 2, in which Ginny grapples with feelings about a parent who is dating. In volume 1, Ginny deals with switching between houses and practical and emotional challenges that come with that. In volume 3, one of her parents remarries; the blended family will also include other children.
