Hillcrest High Boys' School is admitting girls for the first time, and Tara couldn't be more excited. New friends? Check. Cute boys? Check. Mean sister gone? Wrong...

When she discovers Maxie is joining the school too, Tara is crushed. How can she be her own person when her cleverer, prettier sister seems determined to outshine her? And sibling trouble isn't Tara's only problem.

With only ten girls in the year, they're going to have to stick together to survive.

Boys against girls? Bring. It. On.
