For Game of Thrones fans, the TV series may seem like it's been going on forever now. It's been eight long years since we first set foot in Westeros, and we still have a few weeks to go until we're back there for the last time.

For fans of the books, however, it's a whole different story.

George RR Martin, the creator of the series, has been working on A Song of Ice and Fire intermittently since the first installment was published all the way back in 1996 - and it still isn't finished! The most recent book, A Dance With Dragons, came out in 2011 - the same year the TV show started.

Since then, the HBO adaptation has overtaken the books in terms of where the narrative is, but Martin has been involved in the process along the way to make sure that the onscreen version stays relatively true to his original story.

But recently, the author dropped a huge bombshell about the ending.

As it turns out, the finale of the show is not going to be the same as Martin's books - meaning that, if you're a fan of both versions, you'll get to enjoy two quite different endings.

''I've been so slow with these books," Martin confessed, explaining why the show had to go in a different direction to his works. "The major points of the ending will be things I told them five or six years ago. But there may also be changes, and there'll be a lot added.''

And on top of that, Martin also revealed that he was supposed to appear in a cameo in the final season, but he was too busy writing to comply.

''[Showrunners David Benioff and Dan Weiss] invited me to a cameo in one of the final episodes, which I was tempted to do," he told Rolling Stone. ''But I didn't think just for the sake of a cameo I could take the time to return to Belfast.''

Unfortunately, while he gave away what we shouldn't expect, Martin was annoyingly quiet on what we would be seeing in the finale.

Thankfully, a lot of castmembers haven't been able to keep their mouths shut on the same topic, so we've heard plenty of hints from the likes of Kit Harington (Jon Snow), Lena Headey (Cersei Lannister), and Sophie Turner (Sansa Stark). And, just recently, Nicolaj Coster-Waldau (Jaime Lannister) hinted that his character wouldn't survive the last series.

"I had a great last scene. It was absolutely beautiful. It was the perfect way to end," he said.

"Obviously I can’t tell you what the scene was. It wasn’t the final scene (of the series), but it was close to the end and it was shot at a beautiful location. At this point, I had seen quite a lot of colleagues wrap, so I had seen a lot of tears, beautiful speeches, and I knew what to expect.

"I didn’t expect to be emotional, so I don’t know what happened. I had an allergy, there was something in my eye… My final scene was beautiful."

But, who knows - even if Jaime does meet his end in the TV series, he may go to live on in the books. Only George RR Martin can say or sure.
