I love this book! Katie and her awesome friends are now going to be in fourth grade. Katie just noticed something Katie and her friends are going to be split up !!! She was the only one that is going to be in class...4a and they will be in 4b. Now she is soooo sad. So Katie has to be stuck with the new teacher mr.Guthrie. But her friends get mrs.sweet. But Katie is stuck with lots tons of homework.
