The world is a giant underground silo. The outside is toxic. The order of society must be preserved at all costs, lest humanities last outpost crumbles to dust. Of course nothing goes ever wrong.
The story, or maybe rather “the collection of novellas”, follows the events of said Silo, beginning with the old sheriff volunteering to go outside to clean the cameras, and all that unravels from it.

I have devoured this book, and I highly recommend it for anyone up for some… rather dark apocalyptic fiction.

I was also not at all surprised to learn that this was one of the inspirations for Tales: Inside.
