I began পাঠ করা the game of Thrones বই 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 বই pretty closely. There have been some differences but they have been minor and have not affected the সামগ্রিক storyline so far.
However, I feel the epic tale is really only beginning and season 3 will make অথবা break Game of Thrones. I think this because if the প্রদর্শনী continues to follow the বই there will be a lot আরো bloodshed in the 3rd season.
