Wool by Hugh Howey
In a devastated, post-apocalyptic world, the remnants of humanity are living in an underground silo. Even to mention going outside is punishable by death.
When Juliette, an engineer from the ‘Down Deep’ of the silo, is selected to become the new Sheriff, she discovers a shocking secret which puts her life in danger and stokes the fires of insurrection in the repressed population of her home.
In Wool, Hugh Howey gives us a real page-turner of a novel. The tension is ramped up at just the right rate, and the twists and revelations are equally well done. Juliette is a likeable protagonist and the other supporting characters are also well-written.
Although the first book in a trilogy, Wool can be read as a stand alone novel. The ending doesn’t leave you hanging, just eager to read more in the same universe. The next two books in the trilogy, Shift and Dust, cover the origins of the silo and how the story ends, respectively.
