Depressed. Defiant. Possible alcoholic. These are just a few of the terms used to describe fifteen-year-old Jacob Jasper Jones. Lately, though, JJ has a new one to add to the list: detective. He’s been having strange dreams about the fire that killed his parents ten years ago, and he thinks he finally has the clue to catching the arsonist who destroyed his family. A murder investigation isn’t the only thing the dreams trigger for JJ. They also lead to secret meetings with his estranged sister, an unlikely connection with a doctor who lost his daughter in the fire, and a confusing friendship with McKinley, a classmate of JJ’s who seems determined to help him solve the mystery. All JJ wants is to shake the problems that have followed him since that fire, and he’s convinced he must catch the arsonist to do it. But as JJ struggles to find the culprit, he sees there’s more than one mystery in his life he needs to solve.
