Run! Run far away!
LOL, I've read and seen all of it, and I can tell you that the story is compelling - but not for everyone. It's definitely not for kids.
My biggest concern - from a literary standpoint - is that they started making the show before the story was actually finished. And so I wonder how much of the written story has been affected by the show.
Concerning the books; the last installment was published in 2011. If I had to place a bet, it would be that the next (last?) book - The Winds of Winter - will never be finished...
