One day at her dad's house, a young girl finds two old potatoes in the cupboard. ''Gross.'' But before she can throw them away, her dad suggests they try to grow new potatoes from the old ones, which have sprouted eyes. Told from May to September, the potato-growing season, the story includes all the basic steps for growing potatoes while subtly dealing with the parents' recent divorce. Just like the new potatoes that emerge from ugly old potatoes, this dad and daughter move on and make a new life together in the face of unavoidable and unpleasant change. Colorful illustrations throughout and a recipe for mashed potatoes! Paperback. 36 pgs.
