The Rise and Fall of a 10th Grade Social Climber
by Lauren Meehling and Laura Moser
2005

Mimi Schulman follows her newly separated father to New York City. He is back in the city searching to rekindle his fame as a photographer. Mimi is coming back to her onetime best friend Sam, and a new, unusual school, the elite Baldwin School in Brooklyn Heights.

Mimi soon finds that fame looks a lot less preppy at the Baldwin School than it did in Texas. She also finds herself locked into a bet with Sam as to whether she can infiltrate the inner circle of the most popular girls at Baldwin--a diverse group of girls united more by their exclusivity than anything else. So there's a lot of wasted teen behavior going on--partying, substance experimenting, cheating... there's also family shames and secret altruism.

Mimi's bet with Sam spirals out of her control as Sam takes her diary public, leading to all kinds of social ramifications.

A book like this could really only be written by two authors.
