Thirteen-year-old Annabelle struggles in school, no matter how hard she tries. But as soon as she dives into the pool, she’s unstoppable. She’s the fastest girl on the middle school swim team, and when she’s asked to join the high school team over the summer, everything changes. Suddenly, she’s got new friends, and a high school boy starts treating her like she’s somebody special—and Annabelle thinks she’ll finally stand out in a good way. She’ll do anything to fit in and help the team make it to the Labor Day Invitational, even if it means blowing off her old friends. But after a prank goes wrong, Annabelle is abandoned by the older boy and can’t swim. Who is she without the one thing she’s good at?
