Jodi Picoult has done it again: written a thoughtful book on a topical subject, this time school shootings, which gives a new insight into the motives behind such a terrible crime. Nineteen Minutes is the story of a small New Hampshire town torn apart by a mass murder at the local high school. Unlike most school shooters, Picoult's anti-hero has lived to give his side of the story, and his upcoming court case is about to reveal that he might not be the only one who has committed an unforgivable crime... You'll be shocked both by the turns the story takes and by how hard it is to put this book down.
