The latest book in this increasingly popular series focuses on the growing friendship between Abby and the new girl in school, Hannah. When Abby and her new friend, Hannah, take charge of a class project to assemble gift packages for underprivileged children, one thing after the next goes wrong. First their teacher, Mrs. Kantor, must leave school for a few weeks. The class is stuck with a mean substitute who won't let them work on their gift boxes. Then, after their kind principal intervenes and work on the class project resumes, Hannah's baby sister unintentionally destroys many of the gift boxes. Working as a team, Abby and Hannah think of a clever way to save the day, their budding friendship, and the class project.
