George R. R. Martin has once again the release date of the sixth book in his A Song of Ice and Fire series, also known as Game of Thrones, postponed. Fans are there more this year to count, says the writer. “No, winter is not coming”, says Martin in a statement referring to the well-known motto ‘winter is coming’ in the series. Martin brought in 2011 the last part A Dance with Dragons. It was the first book that came out after the successful tv series Game of Thrones started on HBO.
