The author of the hit HBO series, Game Of Thrones, is finally coming clean. He fears the end of the television series, may come well before the books. Talk about spoiler alert!

Fans have often wondered whether the hour-long sci-fi fantasy episodes would be complete before they could in-fact read what happens in George R.R. Martin's "A Song of Ice and Fire" novels. Alas it seems the fear has become a reality.

In speaking at the Sasquan science-fiction convention in Spokane, Washington over the weekend, Martin admitted the ending is a "closely held secret," reports GeekWire. But it has been shared with showrunners, David Benioff and Dan Weiss. Martin said there is a chance the producers will get to the end before he does.

"The show is moving forward like a locomotive, or sometimes a jet locomotive," Martin said. "They're writing 60-page scripts, I'm writing 1,500-page novels. So who the hell knows?

"There was a period where I was worried about that. Then I said, to hell with that. Worrying about it isn't going to change it one way or another. I still sit down at the typewriter, and I have to write the next scene and the next sentence ... I'm just going to tell my story, and they're telling their story and adapting my books, and we shall see," he confessed.

Entertainment Weekly points out, Martin has been in talks with the producers to extend the show a few more season out, in order to complete the novels. HBO agrees, however the cable television company would not want to potentially ruin the creativity behind the show with excessive episodes.

"We know basically how many hours are left in this story," Benioff says. "It's about finding that sweet spot so it works for us and for HBO and, most of all, it works for the audience."

The show is confirmed for a seventh season, verbally confirmed for an eighth by HBO programming president Michael Lombardo, and is looking to air the sixth season in Spring 2016.

On his blog, earlier this year, Martin did shine a glimmer of light on a few more seasons to the HBO series.

"HBO will order season seven, we hope ... AND eight. But even if they just order season seven, that doesn't mean that the show will end in seven; it could just represent a return to the original policy of committing to only one season at a time."
