Instead of being filled with laughter and playing, the playground is full of pouting lips and angry arms pressed tightly together. One student notices something isn't quite right, so she informs the teacher, Ms. Harmon.

Armed with her ruler and a box, Ms. Harmon gathers all those grudges. But first, she helps her students deal with the root of their problems. With her guidance, the children learn how to recognize and let go of grudges. They also practice communicating with others to resolve conflicts in a healthy way.

The pesky grudges are all boxed up, and the playground is no longer infested. Are You Holding a Grudge? is a gentle reminder to children and adults alike that holding onto grudges can weigh us down and make us unhappy. It's a story about forgiveness, understanding, and the healing power of letting go.
