“The show has achieved such popularity around the world, the books have been so popular and so well reviewed, that every time I sit down I’m very conscious I have to do something great, and trying to do something great is a considerable weight to bear,” Martin tells The Guardian. “On the other hand, once I really get rolling, I get into the world. The rest of the world vanishes, and I don’t care what I’m having for dinner, what movies are on, what my email says or who’s mad at me this week because (the book) isn’t out.”
