Cara has never been one of those girls: confident, self-possessed, and always ready with the perfect thing to say. A girl at the very top of the popularity tower. One of the Populazzi. Now, junior year could change everything. Cara's moving to a new school, and her best friend urges her to seize the moment—with the help of the Ladder. Its rungs are relationships, and if Cara transforms into the perfect girlfriend for guys ever-higher on the tower, she'll reach the ultimate goal: Supreme Populazzi. The Ladder seems like a lighthearted social experiment, a straight climb up, but it quickly becomes gnarled and twisted. And when everything goes wrong, only the most audacious act Cara can think of has a chance of setting things even a little bit right.
