Originally published as five linked novelettes, which is why this is also known as “Wool I-V”, this novel is set in a large, vertical underground habitat known as the Silo. The inhabitants are unaware of the outside world apart from the desolate and poisoned terrain they can see on cameras set at the top level of the Silo, which just breaches ground level. The worst crime in the Silo is talking about going outside. The punishment for this is being sent out for “cleaning”, which involves being put into a protective suit and cleaning grime off the lenses of the cameras. After a few minutes the suit fails and the criminal dies in the toxic atmosphere. However, even the cowed inhabitants of the Silo have questions. What happened outside? Who built the Silo? Why is the IT department so mysterious and secretive? Juliette, a woman from the “down deep” engineering levels follows her instincts and stumbles on secrets buried for generations.
Wool starts unassumingly. Silo society is working relatively harmoniously, the vertical design cleverly engineered to ensure social stratification and a lack of unity across departments. However Mr. Howey is not afraid to throw large wrenches in the works for the protagonist as she starts on her odyssey to find the truth. While the second half sometimes drags on a bit, this is a fine piece of post-apocalyptic fiction, and unlike that in some other such “set piece” oeuvres, the setting itself feels well-thought out and plausible.
