At first glance, it looks like a straightforward act of revenge, but things are revealed to be more complex. One of his victims is Matt Royston, the boyfriend of his former childhood friend, Josie Cormier, and others are members of the in-crowd, but others have seemingly no relation. In the days before the trial, and in the days leading up to the shooting, we are given the backstory, told mostly from Josie’s, Peter’s, and their mothers’ viewpoint. We learn of the incessant teasing this boy received, adults’ unsuccessful attempts to help him fit in, and of the stormy relationship between Josie and Matt.

During the trial, we hear from the victims who survived and the devastation the crime has wrought on their lives. In the end, the reader may still be undecided whether Peter is primarily a victim, perpetrator, loyal friend, or all three, but that is the point.
