While all good things must come to an end, Game of Thrones is still going strong as Season 4 winds to a close, with HBO renewing the show for Season 5 and Season 6 back in April. Series creators David Benioff and D.B. Weiss revealed in March that they want to end the show in either Season 7 or Season 8, since author George R.R. Martin has revealed that his book series entitled "A Song of Fire and Ice" will be told over seven books, the last two of which have not been published yet. During a Q&A session on Suvudu, George R.R. Martin's book editor Anne Groell revealed that the author may be planning an eighth book.

When asked by a fan if George R.R. Martin will need more than seven books to wrap up A Song of Fire and Ice, Anne Groell revealed that the series was originally planned as a trilogy, before it grew into a seven or possibly eight-book series.

"I begin to wonder-though 7 is what we currently have under contract. I remember when he called me, years and years back, to confess that his little trilogy was...well...no longer a trilogy. He predicted four books. I said Seven Books for Seven Kingdoms. Then he said five books. I said Seven Books for Seven Kingdoms. Then he went to six. I said... Well, you get it. Finally, we were on the same page. Seven Books for Seven Kingdoms. Good. Only, as I recently learned while editing The World of Ice and Fire (another awesome thing you must buy when it comes out!), there are really technically eight kingdoms, all having to do with who has annexed what when Aegon the Conqueror landed in Westeros. So, maybe eight books for Seven Kingdoms would be okay. Also, he has promised me that, when he finally wraps this great beast up, I can publish the five page letter outlining the bare bones of the trilogy."

While it isn't known when the sixth and seventh books, The Winds of Winter and A Dream of Spring will be published, our report from March revealed that David Benioff and D.B. Weiss met with George R.R. Martin to discuss the ending of his books, since the show is starting to catch up with the novels he has already written.
