It's senior year, and Erika Soto has been rated a nine every week.
After a catastrophic summer that tore her friends apart, the last thing Erika needs to worry about is another layer to Aquino High's complicated, ultra-exclusive social pyramid. At a school where secrets and weaknesses are taken advantage of every day, the senior boys have now decided to rate the girls every week. And if the rating on your Post-It note is low, then you might as well say goodbye to everything.
At first Erika's as swept up in the competition as everyone else. But as her life starts to unravel and her perspectives on everyone she thought she knew change, she has to make a quick decision between living at the top of the pyramid and living with herself. And even if she does choose to take a stand, who's to stay she'll succeed? Can the girls on top really overthrow a system that's years in the making?
