I do have a copy of GoT ebooks but never had the time to read those lol So I'm not really looking forward to the next book.
Also, If I'm not mistaken there are a lot of deviation from the books and the series so I might really need to read it all from the beginning?! XD Most of the comments I've read was that the books was definitely much better than the series though. :)
And You definitely should watch the new season :)
