There are twelve kids in the seventh grade at Fawn Creek Middle School. They've been together all their lives. And in this small factory town where everyone knows everything about everyone, that's not necessarily a great thing. There are thirteen desks in the seventh-grade classroom. Renni's desk is empty, but Renni still knows their secrets; is still pulling their strings. When Orchid Mason arrives and slips gracefully into Renni's chair, the other seventh graders don't know what to think. Who will save Orchid Mason? Or will Orchid Mason save them?
