This book is OK. Pretty violent and kinda sad. Easy for younger readers because it is a graphic novel and there are very few words. I love Nathan Hale's unique style of drawing. The educational value and messages are about the connection between the Pied Piper and the monsters that eat electronics. I hope this review helps cause this is the only one on Common Sense Media! Please add your review if you read it because other readers would love to hear your opinion too!
