In Hugh Howey's Wool, humanity's remnants live in a vast underground silo, one hundred forty-four stories deep, sealed away from a toxic, ruined world. The residents obey strict rules, and the gravest taboo is expressing a desire to go outside—those who do are sent out to clean the sensors, dying while polishing the view. When Sheriff Holston commits this forbidden act, mechanic Juliette is appointed to replace him. As she investigates the silo's hidden past, she uncovers devastating secrets about the authorities, the poisoned exterior, and humanity's true fate. This gripping dystopian story explores control, hope, and rebellion.
