This book is based on the teleplay Dragon in the School by Chris Gifford. I can only hope that the teleplay is better than the book. The story is choppy and confusing. It refers to things in the television show that unnecessarily disrupt the flow. It is in desperate need of an edit.
The concept is simple and suitable for preschool children. The wizard is stealing dragons instead of trying to be their friend. Dora teaches him to respect the animals. I do think this could have been expanded on and made clearer.
The illustrations are typical Little Golden Book quality.
