From TV Insider: 

Season 7 is nearly here. What should readers of the books look forward to?

Diana Gabaldon: One of the things the Outlander production as a whole does really well is battle scenes. We have a certain amount of the [American Revolution’s] Battle of Ticonderoga, the first Battle of Saratoga and a lot of the second Battle of Saratoga, which is the one where Benedict Arnold played a big part. And I absolutely loved the actor playing Benedict Arnold, Rod Hallett. The casting this season has been spectacular. Every character is just right.

Fans are always wondering which books are the basis for each season. What can you tell us about Season 7?

It’s covering An Echo in the Bone [Book 7, published in 2009]and Written in My Own Heart’s Blood [published in 2014].

The show is set to conclude with Season 8. Is there an ending in mind when it comes to Claire and Jamie’s story?

Yes, I have shared the ending scenes with [the creative team]. But as to the actual way that the story [concludes]? No, they don’t know that. [Laughs] But we’ll get there. I don’t write in a straight line, and I don’t work with an outline. This is why it takes me several years to write one of these books — not only the way that I write, which I describe as like playing Tetris in my head, but also just the sheer size and the fact that they are books of a continuing nature.
