I loved this book as much as I loved all of Wool. I really hope there will be so much more of this series. But really, if you haven't read Wool yet, read it before you read this one otherwise you'd majorly spoil your reading fun. I must also add that the atmosphere of this book is so much more depressing than the 5 books before. The characters are - as before - believable and so down-right human, it's easy to forget that they are fictional. I am certainly looking forward to more from Hugh Howey.
