Twelve square miles of paradise make up Nodd, the land of the Grace. It is all seventeen-year-old Jacob knows. Beyond the fence lies the World, a wicked, terrible place, and when the Archangel Zerachiel descends from Heaven, only the Grace will be spared the horrors of the Apocalypse. But something rotten is taking hold in paradise. When Jacob meets Lynna, a girl from the ranch just across the fence, he is tempted to sample the forbidden Worldly pleasures--and his faith, his devotion, and his grip on reality will all be tested.
