This is a very predictable but sweet story of a teenage girl.

From the flap:
When Claudia accidentally eavesdrops on the epic breakup of Paige and Iris, the it-couple at her school, she finds herself in hot water with prickly, difficult Iris. Thrown together against their will into a class production of A Midsummer Night's Dream, along with the goofiest cutest boy Claudia has ever known, Iris and Claudia are in for an eye-opening senior year.
