Here is a story about the oldest of the three little Parlin girls, though so many things are always happening to Prudy that it is not possible to keep her out of the book. The book begins at Christmas with Dotty Dimple said to be nearly three, which should make Prudy about five, and Susy around eight. The book concentrates on the trials that Susy goes through during that winter and ends on the last day of May.
