Doomsday by Design (The Doomsday Chronicles Book 1)

Could it happen? Skeptics and conspirators clash at every turn. Some deny the possibility of a global war while others swear by it as an inevitability... but the debate is over when the world stops turning. The bombs fall, millions die, and a deadly silence looms over the broken world after the damage is done. Perhaps Sandra's crazy, doomsday-prepping uncle was right all along. But now, her Uncle Dorian is missing in action. She'll have to brave the hazards of the apocalyptic wasteland if she ever hopes to see him again. Maybe she should've listened to all those stupid disaster-preparedness lectures after all.
