So, I'm hoping you're a GoT fan...
from what i know he started writing the first boog in 1991
Around there, yes.  The first three books were really good, but the quality certainly dropped after that.
is he still writing the sixth book?
So he claims....  There's no release date nor any indication he's actually working on it.
i heard his inspiration is french historical novels
That rings a faint bell, I could see it.  With so many characters and countries, I guess it makes sense.
ive actually never read one of the novels. i started watching the show though
