1955 novella by Ka-tzetnik 135633?
I remembered it as a very cruel story about the war.
But rereading it, it was rather short, with the "main point" of the story coming in rather late. It's supposedly based on a Jewish gal's diary about how she was sent to a sort of 'camp' where she had to whore herself to the German soldiers.
Not as good as I remember. But I guess its one of those that are supposed to be "classical". A bit disappointed. Some books are better left as a memory i guess.
