Current and Future Projects

Looking for information about Diana Gabaldon's current and future projects? To the best of my knowledge -- and keeping in mind that I have NO inside information whatsoever! -- this is where things stand right now. (Last updated April 6, 2025)
Here is a list of all the current and future books Diana is working on or plans to write in the coming years.
1) Book 10 of the OUTLANDER series
Diana Gabaldon began writing Book 10 in September, 2021. It normally takes her 4-5 years to write one of the Big Books, so it will a while yet before we have any information on when this book might be published. Stay tuned!
2) Brian/Ellen Prequel
Diana Gabaldon is also working on the first of a series of prequel novels (as yet untitled, as far as I know) which will tell the story of Jamie's parents, Brian Fraser and Ellen MacKenzie. In light of the news about a spinoff TV series, BLOOD OF MY BLOOD, I'm sure many of you are curious, but we have very little information yet.
One thing we do know is that the prequel will not be a single novel! In a video interview on September 8, 2023, Diana said:
The prequel is actually three books, fairly short ones. And that's because of the history of the way the first Jacobite Rising fell out. It falls naturally into three historical and geographical periods. So I thought, for the sake of readers, I would try to put it in three smaller books, rather than one huge book. That way they don't have to wait so long.
Stay tuned for further updates as we learn more!
3) Master Raymond book
Diana has said for years that she intends to tell the story of Master Raymond, the first of the time-travelers, but that will probably have to wait until the main series is complete. She is not currently working on this book.
4) WHAT FRANK KNEW book
Diana also intends (eventually!) to tell the story of "what Frank knew". She confirmed on Twitter on February 8, 2023, that WHAT FRANK KNEW will be the title of the book.
That _is_ the title...😊 https://t.co/XMx0jT6Qav

We don't know yet precisely what will be included in this book, but some possibilities include: What convinced him that Claire was telling the truth about the time-travel? Did he find evidence of Claire or Bree in the past?
5) THE OUTLANDISH COMPANION, Volume 3
There will (eventually) be a third volume of the OUTLANDISH COMPANION, covering books 9, 10, and probably other things. Diana is collecting things to put in it, but she's not actively working on this book yet.
6) LORD JOHN AND THE BLACK CHAMBER (novel)
We know very little about this book so far. It will probably include the story of how Lord John and Isobel's relationship developed, as well as how John became involved in working for England's Black Chamber.
7) THE CANNIBAL'S ART (non-fiction)
Diana has talked for many years about eventually publishing a book about writing (the title comes from a conversation between Jamie and Lord John in VOYAGER) but we have no idea when she might start actively working on it. Probably not until the main series is finished.

That's all the information I have right now. Please check back later for further updates.
And IMHO, that last question has to be answered or it isn't finished.
