On December 14, 2012, 26 people at Sandy Hook Elementary School were shot and killed. Nine years on, parents of the young victims are being accosted on the street and harassed online. Conspiracy theorists have asked them to defend that the event even occurred. At the centre of conspiracy theorists' crusade is Alex Jones's InfoWars, where hoaxers air noxious theories. Through exhaustive reporting, narrative storytelling, and intimate portraits, Sandy Hook will be the definitive book on one of the most shocking cultural ruptures of the internet age.
