In this 4th (and final?) book featuring Mr. Terupt and the 7 students who bonded in his 5th grade class, many loose ends are tied up nicely. While the students are finishing middle school, there isn't anything in it that would make it inappropriate for upper elementary students who want to read through the entire series. Each of the students faces his or her own issues, realizes that it is better to ask for help from friends and family, and learns that we are always stronger together. Readers will enjoy seeing their favorite characters go through another year of middle school. Recommended for grades 5 & up. Must read series in order.
