READER BEWARE:
This is not a normal book! It is very short, has no real characters, plot, or motif, and will likely be a poor choice to write a book report or thesis about.
But, if you want a book with a screaming opossum, it has you covered.
The first book in the "Books for Critters" series. The series highlights wildlife loosely based around their popular internet tropes, and raises funds to support the efforts of wildlife rehabilitation organizations.
