A collection of stories spin off from Hugh Howey's World of WOOL... They came to Atlanta to attend the national convention: a retired college professor, an insurance saleswoman, a young couple whose marriage is in trouble, and thousands of others. To their horror, bombs began to fall on the city, and they were herded into an underground silo to protect them from the cataclysm outside. But the silo isn't just a temporary shelter. It's their home now, forever, and surviving there means adapting to the loss of almost everything they knew and loved. The professor becomes a farmer, the insurance saleswoman a teacher. It's going to be a good life, they're told—but is that true, if they'll never see the sun again?
