I don't have TV service, but because FOTs were interested in this series, I got the first book out of the library which I am reading now. Although, this isn't the kind of fiction I usually read, I like it. Cable TV series sell because of the sex and nudity they can display, so I am not surprised to hear about the "Adult content" of the HBO series. Some books are written with that in mind, like the True Blood series, which was very popular.
