Isabel and Zoe are favourite friends - most of the time. They have side-by-side cubbies at school. They never take off their friendship bracelets. And they make each other laugh like nobody else. But some of the time, Isabel isn't Zoe's favourite friend at all. Because some of the time, the fun things they do end in a no-fun way. Like how they've been sent to the principal's office because of Isabel's shenanigans with some kindergartners. Now Zoe is mad at Isabel. Isabel is trying everything to win her friend back. Will getting a new puppy help Isabel mend her friendship with Zoe?
