Anyways the best author in my opinion is Tolkein. But he's like one of those authors that can't have organized writings. Because he's creative but messy. uh..... should I introduce you one of my favorite author??
Bernard werber the writer
He's the french science fiction writer and his books are AMAZING.
ants, death and the origins of the human race! <- those three! READ THEM ALL.
Especially THE ORIGINS OF THE HUMAN RACE is AMAZING. tried to finish them all, but I doubt that you'll get bored with it. Because I guarantee it.
Just type his name and you'll so so many things about him and his books because he's really famous of his works and he's such a sweet guy :) I met him once!
so anyways I guess you're trying to find a real good book since you questioned who is the best author? So good luck with that but I think you already've found one.
CIAO. :)
