The summer Beth turns sixteen, she grows. She grows so fast her bones hurt and she feels like throwing up. Everyone - including Etienne, the boy who lives over the road - looks at her differently. Then she starts catching people. People who are falling out of trees or from tall buildings. Soon Beth discovers that helping strangers sometimes hurts. Sometimes it also hurts or annoys the people she loves. It isn't great for her school grades, either. Is there a way to balance family and friendship and basketball and romance and ... catching?
