Halfway through lunch at the Delaunay, a fashionable European-style brasserie in London, George RR Martin compares the giant slab of breaded chicken on my plate to a map of a fantasy kingdom. The fact that he is one of the world’s biggest-selling fantasy writers, and creator of the books on which the hit television series Game of Thrones is based, makes this a little less surprising than it might otherwise be. But not much. Pointing at my irregularly shaped food with his knife, he elaborates: “There are various little inlets where cities could be,” he says jovially, as if he were making the most obvious comparison in the world.
It’s an entertaining moment and Martin, 63, does seem to be enjoying life. As well he might - 9m copies of his books were sold last year. The five volumes of A Song of Ice and Fire, his dizzying saga of medieval kingdoms locked in internecine warfare, total more than 5,000 pages and there are two more (very long) books to come before the cycle is complete.
The first, called A Game of Thrones, took Martin five years to write, and was published in 1996. By 2005, when the fourth volume, A Feast for Crows, came out, he was a successful genre author, nudging the mainstream bestseller lists. Then, in April 2011, things changed utterly for Martin. Overnight, he became globally famous when HBO, the American pay-TV channel renowned for making high-quality drama, put out the first episode of its new series Game of Thrones. This lavish, faithful, and very expensive (a reported $60m per series) adaptation of Martin’s tale of sorcery – and a lot of sex – became a huge hit. As the second series reaches its climax this week in the US and the UK, it has become HBO’s most successful series, shown in 29 countries and with average US viewing figures of more than 10m per episode. Fans include Facebook founder Mark Zuckerberg, who held a Game of Thrones-themed barbecue (featuring goat and “obscure animal parts”) for close friends last month.
