It's wintertime at Joyce Kilmer Middle School, and everyone is thrilled when school is closed because of a huge snowstorm. Everyone except Jenny, that is! Addie's mom has to work, so Addie's spending the day at Jenny's house. Jenny's stuck hanging out with her former BFF while her friends all go sledding. Thinking about the upcoming school-sponsored ski trip helps get Jenny through the day, but will Addie ruin that for her, too?
