The Critter club books are about these 4 girls who are all different but who all love animals. In the very first book the girls were helpful to one of neighbors and the neighbor was so grateful that they gave them a barn and the girls decide to use the barn to help lost of stray animals. So every book is about a different girl and a different type of animal. Even though it's about the girls helping the animals, boys can like it too because boys I know have read it and like it too. These books are interesting and I think a lot of people will like them! ( )
