Rating: 4.2/5 · Goodreads Hugh Howey's Wool is a post-apocalyptic science fiction novel and New York Times bestseller that takes place in a toxic, ruined world. The story follows a community living in a giant, hundreds-of-stories-deep silo underground, where they believe regulations are in place to protect them. The book explores the mysteries of silo life and human survival, and is told from the perspective of characters like Jules, a heroine who trusts her analytical skills.
