The New York Times Book Review – Stephen King: Perrotta has delivered a troubling disquisition on how ordinary people react to extraordinary and inexplicable events, the power of family to hurt and to heal, and the unobtrusive ease with which faith can slide into fanaticism. The Leftovers is, simply put, the best "Twilight Zone" episode you never saw—not "The Monsters Are Due on Maple Street" but "The Monsters Are Us in Mapleton." That they are quiet monsters only makes them more eerie.
