Note: Although I was provided with free copies of these books, the opinions in this review are my own.
This is a great beginning to a middle grade series aimed at girls. The Pinkaboos are a group of friends who are frights (illustrated as various types of monsters) who attend Fright School to learn how to help little human girls conquer their fears by entering their dreams and chasing away nightmares (who are also shown as monsters).
I quickly became invested in the story, which is imaginative and fun. I liked that it didn't shy away from some dark elements, like a fright who is a school bully becoming a Nightmare. Before starting to read, I wasn't sure if the message of "overcoming your fears" would be too heavy handed, but the authors do a good job of "show, don't tell" and focus on the imaginative details of their invented world.
The illustrations are super cute and playful. I also really liked that there are activities and fun facts at the end, such as the history of the legends of giants, and a worm cupcakes recipe. Each book is quite short (as an adult, it took me about 15 minutes to read each) so I think kids will anxiously be awaiting more stories in the series.
