If you have PJ Masks fans in your house, this book is perfect for you. The first three stories introduce the PJ Masks, their powers, and the villains. The rest are story versions of popular TV episodes. This book helped occupy my 3.5 year old twins for at least 2-3 hours during a 6-hour road trip, and they continue to want to read it and/or flip through the pages themselves every day. Worth every penny.
