Massie Block: With her glossy brunette bob and laser-whitened smile, Massie is the uncontested ruler of The Clique and the rest of the social scene at Octavian Country Day School, an exclusive private girls' school in Westchester County, New York. Massie knows you'd give anything to be just like her.

Dylan Marvil: Massie's second in command who divides her time between sucking up to Massie and sucking down Atkins Diet shakes.

Alicia Rivera: As sneaky as she is beautiful, Alicia floats easily under adult radar because she seems so "sweet." Would love to take Massie's throne one day. Just might.

Kristen Gregory: She's smart, hardworking, and will insult you to tears faster than you can say "my haircut isn't ugly!"

Enter Claire Lyons, the new girls from Florida in Keds and two-year-old Gap overalls, who is clearly not Clique material. Unfortunately for her, Claire's family is staying in the guesthouse on Massie's family's huge estate while they look for a new home. Claire's future looks worse than a bad Prada knockoff. But with a little luck and a lot of scheming, Claire might just come up smelling like Chanel No. 19. . . .

The Clique . . . the only thing harder than getting in is staying in.
