I read this at the end of last year. I enjoyed it on a superficial level, but some parts of it didn't work for me. For example, even though Bruno was only a child, I found it hard to believe that he didn't have a clue what was really going on. I also found in implausible that there could be a hole in the fence big enough for a child to crawl though. My main gripe with the book though was the play on words, such as 'Outwith' and 'The Fury'. Bruno was obviously a German boy, and in the German language, this play on words wouldn't have worked!
However, there were certain parts that I really did enjoy. The man who worked for the family, who was a former Doctor, is the character that really stands out for me.
(By the way, as a long time absentee, I hope it's okay to simply jump in to this thread)!
