Memorial Day weekend is finally here, and Grace Davis is having the best time at the Riverside Swim Club. (RSC to those in the know.) Grace can't wait to spend the entire summer lounging poolside and not sparing a thought for her former best friend, Christina Cooper. There's just one little problem: she doesn't actually belong to RSC. Her parents say she can join if she earns the money for membership herself. With two weeks left in the school year before the summer really heats up, will Grace be able to make enough money, or will her summer be totally sunk?

The 4th of July is supposed to be the perfect summer night at Riverside Swim Club, but expectations are turned upside down when Grace has to fill in for the star swimmer at next week's big swim meet. When frenemy Christina's crush, Mike, offers to help Grace with her swimming, Christina sees the perfect opportunity for Grace to talk to Mike about her. But what if Mike likes Grace instead?

Labor Day is just around the corner. Many of the Riverside Swim Club regulars have gone away for the last days of summer, and some kids are returning from their summer vacations--kids like Nikki Angelo. Nikki is just the kind of funny and carefree friend Christina is looking for, and it isn't long before Christina and Nikki become super close. But when Nikki starts bending the rules, Christina starts getting into major trouble. Will Christina realize who her real friends are before it's too late?
