"Esme Sun absolutely does not care about winning shiny trophies or finally receiving some of the praise her mother bestows so lavishly on her three older, brilliant sisters. But, actually... it would be nice to be good at something. So when Esme discovers on the first day of summer, opening day at the community pool, that her growth spurt over the winter has made her a really fast swimmer, she wonders if she just might have found that thing. After Esme has an uncomfortable encounter at the pool with a new girl, Kaya, Esme worries she may have hurt Kaya's feelings. Then, embarrassed by Esme's awkwardness, her friend Tegan, the cool girl at school who seems to do everything perfectly, makes Esme promise that from now on, she'll be chill, not act so babyish and intense about things--especially not swim team. But when their swim competitions begin, and Esme starts winning, she finds that she actually cares a lot. In fact, she wants to break the pool's freestyle record. That doesn't mesh so well with her promise to Tegan. And as Esme tries to navigate swimming and her friendships, she searches for a way to apologize and make things right with Kaya. Esme's mom's focus on winning confuses her, though, and she begins to wonder: Is winning really as important as she thinks, even if it means being unkind to your friends and teammates? Or is there another way to compete, to be a good sport and a good friend?" -- Provided by publisher.
