:Also, James Clavell Gai-Jin probably qualifies.  Ditto Péter Nádas Parallel Stories (Hungarian: Párhuzamos történetek). 

 :I think what gives is partly that adding a book to the list has one technical hitch: just how many words are there?  I have been unable to find any reference to LOTR with its word count, accurate or estimated (and do the appendices count?).  I have found one website that gives a word count for Gai-Jin.  I have no idea how reliable that is.
