Sydney Frankel, soon to be a sixth-grader, is looking forward to a summer of fun with her best friend, Maggie. She figures she deserves some time to herself to do what she wants before her mom delivers Sydney's new sibling in just four months. Too bad Sydney's mom has other plans for her.

Sydney's forced to take a summer course at the South Miami Community Center. She's allowed to take any class, except for what she really wants--a reading course. But when Maggie comes up with a switcheroo plan so that they can both take the classes they like, unexpected complications arise.
