When cell phones are banned at Branton Middle School, Frost and his friends Deedee, Wolf, and Bench come up with a new way to communicate: leaving sticky notes for each other all around the school. It catches on, and soon all the kids in school are leaving notes—though for every kind and friendly one, there is a cutting and cruel one as well. In the middle of this, a new girl named Rose arrives at school and sits at Frost’s lunch table. Rose is not like anyone else at Branton Middle School, and it’s clear that the close circle of friends Frost has made for himself won’t easily hold another. As the sticky-note war escalates, and the pressure to choose sides mounts, Frost soon realizes that after this year, nothing will ever be the same.
