Claire Lyons is the new girl at Octavian Country Day School, an exclusive private school in Westchester County, New York. But Claire is totally unprepared for the social (and fashion) demands of her new classmates. To make matters worse, Claire's family is living in the guesthouse of one Massie Block, the queen supreme of her new school! And Massie couldn't be less thrilled with the new squatter on her family's estate. Does Claire have what it takes to go toe-to-toe with the "it" girl in her school?
