** spoiler alert ** 
 I finished reading Wool early this morning with mixed feelings. 
 On the surface, this is a very good story. When I started reading it, I couldn't put the book down: I had to read more about the residents of Silo 18, their way of life, and I wanted to know what happened to the world. As the story continued though through the books, information about what really happened became more and more scarce and I felt Howey left details out, letting my imagination do the rest. 
 This might not be too bad if you read Wool as a suspense story and want to know about the characters; but if you're after answers, and you want to know what really happened, you will be disappointed. Howey never delivers. 
 A few of the most burning questions in the series are what is the benefit of cleaning (technically speaking),Why wool,where does IT gets its power from, and how come there are computers fully running in the silos where the rest of the habitats working medieval jobs such as farming, taking care of huge machines and transporting information (porting) by foot. There's a big gap between the different people of the silo in terms of culture and knowledge, which makes the story overall unrealistic. 
 The story also suffers from a slight identity crisis. You think you're reading a future post-apocalyptic tale, but in fact, there's very little going on there. There's suspense, but at the same time, you can guess what happened or bw disappointed with "duh" solution Howey invents out of thin air (suddenly there are huge machines used for digging; there are radios they could use; there's a hidden floor hiding volumes of history). There's romance, but the characters you read about in the first story are mere shadows in the later books (you are left asking yourself why you even bothered with the first 2 books, they could be skipped entirely) 
 However, perhaps this is also because I am struggling to write myself and I know what it takes, I appreciate what the author tried to do and the world he built. It is interesting, has a lot of potential, and it is the first tale in months that captured my mind in a way that forced me to give up sleep and read any chance I got. Perhaps a bit disappointed, but satisfied, I would still recommend this book.
