For some reason I really liked this book. Wool is about a future, hundreds of years from now where all of humanity lives underground in a bunker of sorts with just a few thousand people due to the surface of the planet being uninhabitable. Even though really very little happened, the author was able to create a sufficient mystery that I had to finish it to see how it played out. It is also an interesting idea about how mankind might survive, even if the planet is dead. 

Question: How is write?
Answer: Wool is about a future
