When bookstore employee and indie author Hugh Howey published his short story Wool as a 99-cent ebook on Amazon in July of 2011, he wasn’t banking on the story transforming his career. He didn’t even post a link to the story on his own website. But Wool, about a post-apocalyptic future in which society has been forced to live underground in a vast silo, quickly became the most popular thing he had ever written. By the end of October, the story had made the Kindle sci-fi bestseller list. Howey started to get emails from readers asking him for the rest of the story. There was no rest of the story, so Howey decided to write it.

By January 2012, Howey had self-published five serial stories about that underground silo and collected all five into an ebook, which landed on The New York Times bestseller list by summer. By the end of 2012, Howey had negotiated sweetheart deals with major publishing houses to release print editions worldwide and had even optioned the film rights to Ridley Scott.

As Wool opens, Holston, the sheriff of the silo, is being sent to “cleaning,” a punishment that takes him to the toxic surface to scrub the sensors that project a view of the world above to the silo below. The description of the view is one of the only clues Howey provides about the world before the silo was created. It’s a “familiar and rotting skyline” in which “ancient glass and steel stood distantly where people, it was suspected, had once lived aboveground.” Like his wife, who had been sent to cleaning three years prior, Holston had committed the worst sin imaginable in the silo: asking to go outside. In Wool, cleaning is death sentence and human sacrifice: The pressure felt by thousands of people underground grows “like steam building up in the silo, ready to launch something out” and is transferred to one person, purged in an act conceived to remind the community that their silo is a shelter, not a prison.

Of course, the silo feels like both, and that tension is at the heart of the book. Holston’s cleaning sets off a chain of events that transition the action from short story to serial novel. Soon, the mayor of the silo needs to appoint a new sheriff and selects a smart and strong-willed candidate from the silo’s mechanical department named Juliette. Juliette becomes obsessed with figuring out Holston’s motivations, and her subsequent determination to uncover the truth about the silo’s history and who’s really in control of it creates the powder keg for an uprising within the silo. The escalation of anger to fissures within the silo and then finally to conflict is rendered deftly, and the pace at which Howey reveals the inner workings of the world of the silo makes Wool a page-turner.

The intrigue of Wool (the title comes from the scrubbers used by people sent to clean the sensors on the surface) is enjoyable and thought-provoking. Howey borrows from our present to make the book resonate. In many ways, the silo is a triumph of human survival and sustainability. It’s an energy-independent community with 100 percent employment and universal access to education and health care. But it’s also a carefully designed system with zero population growth, a lack of media and social stratification created by the architecture of the silo. More than 100 floors deep and connected by only a narrow circular staircase, the silo is designed to limit mobility and communication, separating the mechanical department at the bottom, the mayor and sheriff up top, and the IT department as far away from both of them as possible. Readers’ fascination is powered not by the novelty of the silo but the frightening familiarity of it. While most post-apocalyptic fiction invites us to imagine how civilization might evolve after the world as we know it ends, Wool instead invites us to imagine what it might take — and what the costs might be — to prevent civilization from ever evolving beyond where we are right now.

Howey also taps into many of our current anxieties. Who controls the flow of information to all of our screens? How much privacy and control are we willing to give up to ensure domestic security? And how much good will it do to know the truth if you can’t change the system? It’s this last question that fuels uprising in the silo. Knox, the head of Mechanical who rallies his colleagues and others to revolt, explains why his anger compels him to violence: “I only want to hurt those that lied,” he says. “That’s all any of us want. We’ve all lived in fear. Fear of the outside. Fear of cleaning. Afraid to even talk about a better world. And none of it was true. The system was rigged, and in a way to make us hang our heads and take it.” Being in the silo is like living in a world where the decisions were made a long time ago by people you didn’t vote for. Sound familiar?
