Perfect book series!
Format: Hardcover
This book series is incredible! There are several and they are all so smartly written and the illustrations are both fun and cute. As a former teacher, I love books that teach life lessons and this series is all about being kind, not always needing to fit in and how to make yourself feel good so you can make others feel good.
