The Boy Who Changed the World by Andy Andrews is a wonderful children's story based on the "butterfly effect." The focus of the book is to help children understand that each action, whether good or bad, affects someone else. Andrews, in his own unique way, takes you through the life of not just one boy, but four boys who changed the world through a ripple effect. Each one's actions affected the actions of the next, and in the end, the world was changed.
I found this book to be well-written, interesting, and educational. In fact, it is one of the best children's books I've seen come out in a while. Through it, children learn about some important people in history and are given the challenge to go out and change the world through their own actions. The story and lesson are intriguing. The illustrations are fantastic and really make the story come alive to the reader. I highly recommend this book to readers of all ages.
