“Winds of Winter”, the sixth book of Games of thrones series is yet to be confirmed a release date. Several deadlines have already passed. But that’s not making the news now; the author of the fantasy saga George RR Martin stated that one cannot expect a happy ending in his sixth book.
The news in his own words “There are a lot of dark chapters right now in the book that I’m writing. It is called The Winds of Winter, and I’ve been telling you for 20 years that winter was coming. Winter is the time when things die, and cold and ice and darkness fill the world, so this is not going to be the happy feel-good that people may be hoping for. Some of the characters [are] in very dark places.
In any story, the classic structure is, ‘Things get worse before they get better,’ so things are getting worse for a lot of people.”
It is being rumored his sixth and seventh (Dreams of Spring) books will be released together but the author has rejected the statement. The good news is HBO will be premiering the seventh season soon. So we could say at least before the eight seasons the sixth book would be published.
