A little competition can be healthy, as HarperCollins proved on its recently concluded Class Acts tour. The publisher’s first middle-grade group tour, Class Acts visited schools and bookstores in 11 national markets and pitted a dozen authors against one another in friendly competitions. During the school events, which often took on the atmosphere of a pep rally, students were split into two teams, each led by a different visiting author. Teams went head to head in several rounds of competition, including a class cheer round, a trivia round, and an “ask the author” round. The team who earned the most points won a set of books for their classroom library. Shown here, a selection of photos from the Class Acts yearbook.
