Back in March 2026, Outlander author Diana Gabaldon reassured fans that the show would have a satisfying ending. With season 8 coming to an end, Gabaldon shared her thoughts on a future adaptation of Book 10 of the series.

Gabaldon told Parade that, given the limited time, Book 10 would’ve been impossible to adapt for Outlander, in what would presumably have been season 9. But when pre-production started for season 8, Gabaldon said that the book was “nowhere near being done.”

She has stated, however, that she has partially stepped back from the show’s production in order to finish writing Book 10, hopefully aiming for a release date either at the end of 2026 or sometime in 2027.

Diana Gabaldon is open to having Book 10 adapted

Regarding the possibility of adapting the last book of the series, Gabaldon said: “After Book 10 comes out, someone can decide if they want to do something televisual with that or not.” When asked if she would be okay with that happening, she said it would depend on who was taking on the project, and that she would hope for it to be the same people who have been working on Outlander for nearly a decade.

When the show outpaces the books

Gabaldon has long criticized while also praising the adaptation of her best-selling book series. She recently talked about how some of the changes that were written in the show took the narrative too far from the beloved book series, in particular a major character’s death in Episode 7.

The ninth book of the series, Go Tell the Bees That I Am Gone, was published in 2021, when the show had just been renewed for its seventh season. Fans had hoped Book 10 would eventually be published in time for the last Outlander season, giving the show source material for its ending.

Alas, as Gabaldon said herself, show business is a “very active industry” and “a book moves a lot more slowly.” We don’t really blame her for taking so long to finish her story. It’s a beloved series that deserves a proper ending, just like Outlander needed its finale to remain faithful to the original story.

The growing Outlander franchise

Between the sequel series Blood of My Blood and this statement from Diana Gabaldon, the Outlander franchise could grow in many directions. Since season 8 has been marked as the last season of the show, we don’t expect a season 9, following Book 10.

However, we have speculated on a possible expansion towards the big screen. Certainly an Outlander movie would be welcomed by fans. In the meantime, we’ll have the second season of Blood of My Blood to keep us sated in the fall.

The Outlander finale is now out on STARZ.

Outlander showrunner breaks down the series finale—and the storylines that didn’t make the cut

After eight seasons, Outlander has come to an end. Many fans still have doubts about that last scene.

In an interview with Entertainment Weekly, Outlander executive producer and showrunner Matthew B. Roberts reflected on the finale’s biggest mysteries, the emotional post-credits sequence, and several storylines the show never had time to fully explore.

The final episode left viewers questioning the fate of Jamie and Claire Fraser after the Battle of King’s Mountain. Rather than providing definitive answers, Roberts intentionally designed the conclusion to remain open to interpretation. He explained that the supernatural core of the series influenced that decision. “There’s magic in Outlander,” said Roberts. “I have to remind people, [Claire] came through time.”

An ending open to interpretation

Roberts revealed that he always intended to bring Jamie’s ghost back into the story to create narrative symmetry with the pilot episode. According to him, the ending reflects the cyclical nature of the romance at the center of the show. “This is my interpretation — and everybody should have their own — that this is never ending and never beginning,” he said.

When asked directly whether both Jamie and Claire survive, Roberts refused to give a concrete explanation. Instead, he responded: “You tell me–I’m not going to tell any single fan how to interpret that last beat.”

The showrunner hinted that the finale contains subtle clues for attentive viewers, especially during the sequence where Claire grieves over Jamie’s body. Before the episode cuts to Jamie’s ghost in Inverness, we can see a faint blue light emanating from Claire’s chest. As book readers may already know, that’s the clear sign of Claire’s magic working on Jamie to revive him.

Roberts deliberately avoided clarifying the symbolism behind the moment. He stated that audiences should form their own emotional conclusions from the story. If viewers miss the blue light, the ending becomes far more ambiguous—which is exactly what contributed to the widespread confusion.

Jamie’s ghost as a full-circle moment

Roberts also addressed the long-running mystery surrounding Jamie’s ghost from the first episode. He confirmed that the Highlander figure seen watching Claire in the original pilot was indeed played by Sam Heughan all along. “That was, to me, one of the great full-circle moments,” Roberts explained, noting Heughan wholeheartedly agreed on the narrative choice when production on the final season began.

The finale additionally featured a post-credits scene that served as a tribute to the people who worked on the series from the beginning. Roberts described it as “our love letter and a thank you to all the crew that had been there from day one.” He added that the sequence was also meant to honor Outlander author Diana Gabaldon.

The storylines that Outlander didn’t finish… yet

Although the series wrapped up many major arcs, Roberts admitted there were still several stories he wished the team had more time to explore. He specifically mentioned Lord John Grey, William’s evolving storyline, and additional scenes involving Fanny, Jamie, and Claire as missed opportunities due to time limitations.

“There are so many other stories in the books that we certainly would have loved to have tried to do or spent more time with the character,” Roberts stated. “There are so many amazing characters that it’s hard to pinpoint just one. John Grey’s character is so fantastic. There are books, you know, I might want to look at doing something there. With William, that storyline, to go off and see what happens to him and how that affects Jamie and build that. And then the Fanny storyline — not just where she goes, but more scenes with her and Jamie, and more scenes with her and Claire. I think that would have been lovely to build out too, but we just didn’t have enough time.”

Many fans share the same sentiment, as most of these storylines feel abandoned now that the show is over. Especially Fanny and the revelation that she’s a time traveller. Will we ever learn what role that revelation was meant to play in the overall story? Nothing came of it in the finale, after all. For this reason, theories of a possible film feature have begun surfacing online.

It’s not a far-fetched thought. Diana Gabaldon herself has talked of a potential adaptation of Book 10 of the Outlander series. The loose ends left by season 8 could come together with the new material from the upcoming book and make it possible to relive Outlander at least one more time. One can only hope.
