Wool by Hugh Howey is a short but worthy read. The author masterfully conveys the feeling of desperation, doom, and unrest that stem from questionably voluntary living/imprisonment in the confines of a giant concrete underground shelter in the toxic world, as well as the overpowering need and drive to find out whether there is truth in the faint but forbidden hope that there just may be something better outside. For such a short book, the themes are very well-developed. The narration is great, the pacing and the feeling of suspense well-realized. The ending may be a surprise for some readers or the inevitable conclusion for others, but it is shocking regardless. On to the next installment immediately. The bleak and terrifying world of Wool is somehow addictive, and I want to find out more!
