This book is amazing! It talks about the main character, Russel, who encounters a bully named Richie. He and his friends Catalina and Elliot do an "experiment" like scientists and try to find out why Richie is bullying Russel. Catalina is also facing bullying with a popular girl, Bethany Demere. Elliot, lastly, is facing bullying as well. 3 boys have picked on him for the longest now and he hates it. They all go through modern day bullying: Bullying for Jealousy (Catalina) and Bullying Physically (Russel and Elliot). This story basically explains life in middle school. This is definitely a good book to read for 4-6 grade students! :)
