One small act of kindness can change the world. From esteemed bullying expert and author of The Invisible Boy, Trudy Ludwig and Little Elliot illustrator Mike Curato comes a tale as simple - and simply inspiring - as the golden rule.

When one child reaches out in friendship to a classmate who seems lonely, she begins a chain reaction of kindness that ripples throughout her school and her community. One kind act begets another, small good deeds make way for bigger ones, and eventually the whole neighborhood comes together to build something much greater than the sum of its parts.

From acclaimed bullying expert Trudy Ludwig, The Power of One not only conveys a message of kindness, it offers concrete steps that kids can take to make a difference in their own communities.

As Trudy says in the final line of the book- "Acts and words of kindness DO count, and it all starts with ONE."
