Thirteen-year-old Henry's happy, ordinary life comes to an abrupt halt when his older brother, Jesse, picks up their father's hunting rifle and leaves the house one morning. What follows shatters Henry's family, who are forced to resume their lives in a new city, where no one knows their past. When Henry's therapist suggests he keeps a journal, at first he is resistant. But soon he confides in it at all hours of the day and night.
