Another fabulous book written by Kevin Henkes about friendship and acceptance. This is a humorous and heartwarming tale of two inseparable mice learning to make room for one more friend. At first, Chester and Wilson were unsure of the "new mouse" in town. However, after Lilly scares away some mean bullies, the mice quickly changed their opinion of her and discover they have many similarities with their new friend. This book can be used in a variety of ways in the lower elementary grades. I would have my students do a character trait study and compare and contrast how the characters change from the beginning of the story and the end of the story.
