The book that won a Newbery award actually shouldn't have! It is overly focused on the environment, which might seem like a good thing at first glance. However, when it comes to the overall quality of the story, it falls short. The plot may be lacking in depth and excitement, and the characters might not be fully developed. Just because a book has an environmental theme doesn't mean it automatically deserves a prestigious award like the Newbery. There are many other aspects that need to be considered, such as the writing style, the pacing of the story, and the ability to engage the reader on multiple levels. In this case, it seems that the environmental aspect overshadowed the other important elements, resulting in a book that is not very good despite its award.
