Ways to Share Joy (A Ryan Hart Story, 3) by Renée Watson

Ryan Hart is caught in the middle. She has an older brother and a new baby sister, and she's in a friendship tug-of-war with two friends who both want to be her best best friend. How can Ryan think about being kind to a classmate who is relentless with his teasing? Or be her signature sunny self when her brother, Ray, pulls the ultimate prank?

But even when it seems like nothing is going her way, Ryan still looks for a way to see the bright side of things, refusing to let anything steal her joy, and finding ways to share it with everyone she meets.
