The Sound Of Your Voice by Frances O’roark Dowell

In the conclusion to the bestselling Secret Language of Girls trilogy, Marylin and Kate find that boys can be just as complicated as friendship.

Marylin knows that, as a middle school cheerleader, she has certain obligations. She has to smile as she walks down the hall, be friends with the right people, and keep her manicure in tip-top shape. But Marylin is surprised to learn there are also rules about whom she’s allowed to like—and Benjamin, the student body president, is deemed unnacceptable.
