The Children's Literature Laureate, Joseph Coelho, tells the story of a furry monster that separates two best friends. There is only one little word that can chase it away! This big furry monster slowly grows, eroding everyone's fun. However, this is not just an ordinary monster. It's a furry disagreement that refuses to leave. They try to offend it, yell at it, and even ignore it. Nothing works. "The disagreement came out of nowhere. It sat huge and swollen in the middle of the yard between me and my best friend." Until the best friends say that little word that makes everything better. They learn how to shrink the monster until it disappears completely. And soon, they can't even remember what it looked like! We all know how a disagreement can swell into something we never expected. What starts as a simple annoyance has the power to truly hurt our feelings. This book perfectly describes those intense emotions and provides a comforting solution in the form of an apology, offering peace and reconnection to friends. The perfect metaphor for difficult conversations that can hinder daily life and a gentle introduction to the concept of compromise for your child. Coelho's tender and lyrical verses are perfectly paired with the classic illustrations of Allison Colpoys, creating a book that will be appreciated by young readers. This is a tribute to the power of an apology and to valuing a special relationship that is deeper than friends ever realized.
