Will "A Song of Ice and Fire" and likewise "Game of Thrones" have a happy or destructive ending? According to its author George R.R. Martin, it will be a little bit of both.

"I think you need to have some hope," he told Vulture. "We all yearn for happy endings in a sense. Myself, I'm attracted to the bittersweet ending."

Martin has earlier revealed that he wanted to liken the ending of his novels to the ending J.R.R. Tolkien wrote for his "The Lord of the Rings" trilogy. In "Return of the King," Frodo Baggins and his group managed to destroy the ring; however, they came home only to find it destroyed by war.

"I think Tolkien did this brilliantly," said Martin.

There are still two more novels left to Martin's series, and there is some concern that the show might wrap up first before the author finishes it. Martin said that he feels the pressure, although he does not want to sacrifice the quality of his story just to end it on time.

"I've been hearing them come up behind me for years, and the question is: How can I make myself write faster? I think, by now, the answer is I can't. I write at the pace I write, and what the show is doing is not going to change what the books are," he admitted. "I started writing about these characters and this world in 1991, and we didn't have the first meetings to create the show until 2008, so I got like a 17-year head start!"

His latest book, "A Dance With Dragons" was released in 2011, while the next one called "The Winds of Winter" is said to arrive before the sixth season begins.

The "Game of Thrones" series, meanwhile, is currently in production for season six. They have already exhausted Martin's novels to the point that they need more published material, although season five only proved that they can veer away from the storyline a bit, but still come to the same conclusion.

One of the changes they made was in Sansa Stark's storyline. In the novels, Sansa does not marry Ramsay Bolton, and the sadistic son of Roose Bolton actually married Sansa's best friend Jeyne Poole, thinking it was her.

Another glaring difference is the death of throne contender Stannis Baratheon, who was finally killed last season by Brienne of Tarth.
