Unpleasant remarks on a student's social media account causes cell phones at Branton Middle School to be banned.  The need to communicate is strong in this population, so they begin using the post-it notes they were required to buy at the beginning of each school year.  Frost, nicknamed after the poet Robert Frost after winning a fifth-grade writing contest, and his three middle school buddies make the perfect group.  Bench, DeeDee and Wolf all have nicknames derived from their talents and they depend on each other to get through school each day.  Most importantly, they eat lunch together at their own table - made for four people.  Life is good - until a brash new student, Rose, shows up at their lunch table.  As Rose quickly inserts herself into the group's after school activities,  she is accepted by some of the group, but not all.  At the same time, the post-it notes are beginning to voice negative and bullying messages.  Will this group of friends survive the peer pressure?  Readers will root for these approachable characters and their stories.
