I began Leggere the game of Thrones libri many years ago. I recently re-read the first 5 and can't wait for season 3 of Game of thrones to start!
So far the Game of Thrones TV series has followed the libri pretty closely. There have been some differences but they have been minor and have not affected the complessivamente, generale storyline so far.
However, I feel the epic tale is really only beginning and season 3 will make o break Game of Thrones. I think this because if the mostra continues to follow the libri there will be a lot più bloodshed in the 3rd season.
