Seventeen year old Stella Banks has just graduated from high school and can't wait to spend the summer reading and enjoying relaxing before she has to start college next year. That is until her mom comes to her with an offer. To be a stay-in nanny for her mom's best friend for the summer. Stella doesn't hesitate to take the offer, knowing that she will be getting payed so much she won't even have to pay for student loans. Plus she gets to stay in a nice mansion. She doesn't think anything can ruin her happiness. Until she finds out her mom's best friend has nine kids. Nine kids who are all completely irresponsible, messy, conceited, and are set on making Stella's life at their house a living hell. Can Stella make it through the summer without tearing her hair out? Can she make it through the summer without falling in love with the oldest Carter who also happens to be her ex- best friend? With first kisses, first dates, and an empty fridge, can Stella manage to survive life with the Carters?
