The sparks fly in this heated addition to Spotlight's swim clubcentric tween series. The 4th of July is supposed to be the perfect summer night at Riverside Swim Club, but expectations are turned upside down when RSC's star swimmer, Jen Cho, breaks her leg! The next morning, the coach tells Grace she'll have to fill in for Jen at next week's big swim meet. The problem? Grace is a totally terrible swimmer. Meanwhile, Christina is trying everything under the sun to get Mike Morris to notice her. When Mike offers to help Grace with her swimming, Christina sees the perfect opportunity for Grace to talk to Mike about her. But what happens when it seems that Mike likes Grace instead? And when Grace starts to realize that she might like Mike's best friend best? One thing's for sure: It's the heat of the summer and the sparks are about to fly!

Growing up, Cassie Waters spent every waking moment of every summer at her swim club (which was conveniently located at the end of her street). These days, Cassie lives in the suburbs of New Jersey, writing and editing books, hanging out with friends, and having lots of fun. Over the years, Cassie has written dozens of books, but the Pool Girls series is nearest and dearest to her heart. She doesn’t make it to the pool nearly as often as she would like these days, but she is still very good friends with the girls she used to hang out with at her swim club.
