Mouse is so annoyed and decides to make one small change - planting a flower. It reminds everyone of the way Sunnyville used to be. As the other animals again follow suit, they can take charge and change their town for the better.
What I loved: This book has a simple and clear message about personal responsibility and consideration. It comes across throughout the story. The repetitive nature of the text makes this a great book for young readers, and a low word to picture ratio also makes this great for young children or those who really enjoy illustrations. The pictures here are fantastic with lots of color and animals that make each page fun to look at and dive into the details.
What left me wanting more: In scenes where Sunnyville is getting more chaotic, there are scenes of animals being physically mean (for instance ones hitting the others on the head) and destructive (for instance, an animal smashing a boom box with a mallet). These add to the chaos and depiction of inconsideration, but may not be great examples for children as the message is conveyed without these inclusions.
Final verdict: IT'S ONLY ONE is a fun picture book that shows children how they can make a difference with a small act - for better or for worse. With great illustrations, this picture book conveys a clear message asking the reader to take responsibility for their actions, as it is never only one.
