Query: Excellent (in English anyway!)

I have read only the English translation of this book ("The Reader") but I can recommend it as an excellent novel. The story takes some interesting twists and time jumps but isn't difficult to follow - it's very well-written. If you can, try to avoid finding out anything about it before you read it. The language wasn't particularly difficult, but I'd imagine you'd have to have pretty good German (or a good dictionary and a lot of patience) to read it in its original language; it's no kids book. A really interesting insight into post-WWII societal guilt in Germany.
