Lately I was thinking about buying the books from that series, but I'm not really sure if it is worth it. One friend of mine said I would get basically the same story from watching Game of Thrones(with much more nakedness, he added), but I don't know, adaptations from books are never as good as the books themselves. Another friend of mine said it is completely worth it, and now I'm divided. Here in Brazil the price tag is around 45~50 reais(around 25 US dollars) on most places I've seen, but in the internet I've found some sweet deals for 35 reais.
There is also the option to rent it but eh, I don't know, I would rather just buy them already.
