Will do - the German tile is Die Sterne von Eger, I think it has been translated a long time ago. You should give it a try if you can. It's a nicely written book, with a clear enough style for it to be Pflichtlektüre in the 6th term. I was about ten when I first read it, myself. It's not a children's book, though, even if the main characters are childen at the beginning.
