Well, here's the list. The reason I said it was biased is because it includes only my top 10 authors.

. Anyway, vote for your number one from this list. If you haven't read any of their numerous works then you are technically a heathen (and don't ask me why so because I don't answer to heathens

). Furthermore, as postulated by Mill, you should not be treated as human since you possess no rationality and thus are debased and idiotic

.
Anyway, before I go on this course of idle banter far too long, I would like to point out that if you absolutely must, you may (and see here,
I actually give
you permission) post your own favourite author if he/she is not listed.
It would also be nive to hear your reasoning behind your choice, such as: "OMFGZOR that book owns", or, if you possess more time on your hands and a shred of intelligence, something such as: "The superb imagery and dynamic plots intertwined with well formed and riddled subplots make this epic absolutely and unabashedly stand out from the rest".
My vote goes for: hmmm, actually difficult this one, I'll leave it a while longer during which time I'll give it a lot of thought.
Semi-heathen reporting ... I had to vote Tolkien because I have only read him and Pratchett from your list, and of the two, Tolkien wins out imo. Not sure I can honestly claim to have any remaining shreds of intelligence after a day in Diablo so I won't attempt any pretentious imagery or comments.
Suffice it to say that your post did make me chuckle and I have to admit that my curiosity has been piqued. This is clearly a genre I have overlooked to this point. Oversight corrected and the authors and recommendations have been added to extended reading list filed neatly in dusty in-tray under JSP updated price list
