Spun off from Hugh Howey's World of WOOL... Lexie Brownell never expected that a simple trip to Atlanta with her children would change their lives forever. Instead of continuing on to Orlando to visit the theme parks, the Brownells and thousands of their fellow Californians are herded into an underground silo, where they’re told that the outside world has been destroyed by a nuclear attack. That the silo is now their home, and always will be. But people don’t change, simply because they’re trapped underground—as Lexie and her family soon discover. Hopes and dreams, determination, compassion, and loyalty all survive… as do one man’s need to surround himself with stolen goods, and a boy’s despair at being bullied. Trapped in the silo, these former Californians have to create a new life... unaware that they're being watched. And judged.
