On where Martin is with the book series
Martin: Well, I'm writing book 6, The Winds of Winter. I'm starting to worry because everybody keeps asking me, "What are you going to do, if David and Dan and the show catches up to you?," and I didn't think it was a problem before, but they're moving faster than I am and it's beginning to scare me. I have not failed to notice this. I feel sometimes as if I'm laying track for a railroad and I can hear the locomotive coming up behind me. It's building speed and I see the smoke and I hear the whistle coming, and I better keep laying that track pretty fast 'cause I'll get squashed, if the locomotive comes. But, I still have a pretty considerable lead, or at least that's what I'm telling myself. Season 3 is only the first half of book 3. Season 4 will be the second half of book 3. And then, I have book 4 and book 5, and those are gigantic books which have to be recombined because they're actually parallel. I'm hoping those will be at least two seasons, maybe three. That will give me some time to finish book 6. By the time they're doing that season, I'll be writing book 7. That's my story, and I'm sticking to it.
