Few modern science fiction series have developed as passionate a following as Martha Wells’ The Murderbot Diaries. What began with All Systems Red has grown into one of the most acclaimed and recognizable sci-fi series of the past decade.
Now that Platform Decay has joined the series, readers are naturally looking ahead and asking one big question:
When is Murderbot Book 9 coming out?
Martha Wells has not announced an official release date for the next Murderbot Diaries book, but there are already some important clues about the future of the series. Wells has discussed writing another Murderbot novel and has also indicated that the next installment could potentially bring Murderbot’s story toward its conclusion.
Here is everything we currently know about Murderbot Book 9, including its possible release date, whether another book is confirmed, what the story could explore, and whether Book 9 might be the final entry in The Murderbot Diaries.
Is There Going to Be a Murderbot Book 9?
The good news for fans is that Martha Wells plans to continue Murderbot’s story with another novel.
There is currently no official title or publication date for Murderbot Book 9, but Wells has spoken about another installment being part of her plans.
That means Platform Decay is not necessarily the end of Murderbot’s journey.
The bigger question is whether Book 9 will be the final Murderbot book.
Wells has suggested that she has begun thinking about how Murderbot’s larger story should eventually end. Because of that, there has been speculation that the ninth main installment could serve as the conclusion to the series.
Nothing should be considered completely final until Wells and her publisher make an official announcement, but fans should prepare for the possibility that the next Murderbot novel could be a particularly important one.
When Is Murderbot Book 9 Coming Out?
There is currently no confirmed release date for Murderbot Book 9.
Readers hoping to preorder the next installment will therefore have to wait for an official announcement from Martha Wells or Tor.
Looking at the publication history of the most recent books, however, gives us at least some idea of how long the wait could be.
Recent Murderbot releases include:
- System Collapse — 2023
- Platform Decay — May 5, 2026
- Murderbot Book 9 — To be announced
There was a gap of roughly two and a half years between System Collapse and Platform Decay.
If Wells follows a similar schedule, a 2028 release for Murderbot Book 9 would be a reasonable possibility.
That is only speculation, however.
The next book could arrive earlier or later depending on Wells’ writing schedule, other projects and when the publisher decides to place the novel on its release calendar.
For now, readers searching for the Murderbot Book 9 release date should consider the official answer to be:
Murderbot Book 9 does not have a release date yet.
Could Murderbot Book 9 Be Released in 2027?
A 2027 publication date cannot be ruled out, but there is currently no official indication that the novel will arrive that soon.
Publishing schedules can vary significantly from one book to another. Even after an author finishes a manuscript, editing, production, marketing and scheduling can add considerable time before a book reaches stores.
Because Platform Decay was released in 2026, a 2027 release would represent a relatively short turnaround compared with the gap between the previous two books.
For that reason, 2028 may be the safer prediction, but fans should treat any date as speculation until an announcement is made.
Will Murderbot Book 9 Be the Last Book?
Possibly.
One of the most interesting developments surrounding the future of The Murderbot Diaries is that Martha Wells has discussed thinking about how the series should end.
That has led many fans to wonder whether Murderbot Book 9 could be the final book in the series.
Wells has never treated Murderbot like a franchise that must continue indefinitely. Much of the appeal of the series comes from the slow development of its central character, and that journey may eventually reach a natural conclusion.
If Book 9 does become the finale, it would bring an end to a remarkable science fiction run that began with All Systems Red.
At the same time, readers probably should not assume that Murderbot will definitely end with Book 9 until Wells confirms it.
Plans can change during the writing process, especially when dealing with a fictional universe as expansive as this one.
Platform Decay Sets Up the Next Murderbot Book
Platform Decay continues Murderbot’s story following the events of System Collapse while pushing several of the series’ biggest themes further forward.
Without getting into major spoilers, the latest novel continues exploring questions that have followed Murderbot since the beginning.
What does freedom actually mean when you were created to be property?
How does Murderbot define itself once it is no longer controlled by a governor module?
What responsibilities come with independence?
Can Murderbot build meaningful relationships while remaining deeply uncomfortable with emotional intimacy?
And perhaps most importantly, what kind of life does Murderbot actually want?
Those questions have always existed underneath the action sequences, corporate conspiracies and sarcastic commentary that make the series so entertaining.
If the next Murderbot book really is approaching the end of the story, those themes could become even more important.
What Will Murderbot Book 9 Be About?
No official synopsis for Murderbot Book 9 has been released.
Until Martha Wells or the publisher reveals more information, specific plot predictions remain speculation.
Still, the direction of the series gives readers several possibilities for what the next book might explore.
Murderbot’s Fight Against Corporate Power Could Grow
Corporate exploitation has been one of the defining elements of The Murderbot Diaries from the beginning.
Murderbot exists because corporations created constructs designed to protect humans while simultaneously treating those constructs as disposable property.
Companies such as Barish-Estranza represent the larger system Murderbot has spent much of the series resisting.
A final Murderbot novel could expand that conflict.
Rather than simply surviving another dangerous mission, Murderbot may eventually have to confront some of the larger institutions responsible for creating and exploiting SecUnits.
That could give the series an appropriately large-scale conflict if Wells is truly preparing to conclude the story.
Murderbot’s Personal Journey Will Probably Remain the Focus
Despite all of the spaceships, killer robots, alien technology and corporate villains, The Murderbot Diaries has always been a character-driven series.
Murderbot’s internal journey is arguably more important than any individual mission.
At the beginning of the series, Murderbot mainly wants to avoid humans and watch entertainment media.
Relationships are dangerous.
Emotions are inconvenient.
Human interaction is exhausting.
Over time, however, Murderbot begins forming connections despite itself.
Those relationships never magically transform Murderbot into a completely different character. That is part of what makes the development so satisfying.
Murderbot grows while still remaining Murderbot.
If Book 9 does become the ending, readers can expect Wells to continue exploring that development rather than suddenly changing the character’s personality.
Could We See More Free SecUnits?
Another fascinating question hanging over the series involves the future of constructs like Murderbot.
Murderbot’s freedom is unusual.
Most SecUnits exist as corporate property, controlled through technology that severely limits their independence.
Murderbot secretly hacking its governor module is what makes its entire journey possible.
But that raises a much bigger question:
What happens if other SecUnits become free?
The answer could reshape the entire world Wells has created.
A future Murderbot book could explore what happens when artificial beings created for corporate security begin demanding autonomy.
That theme would also connect naturally with the series’ longstanding examination of personhood.
Why Murderbot Became One of Modern Science Fiction’s Best Characters
The popularity of Murderbot comes from an unusual combination of characteristics.
Murderbot is incredibly dangerous.
It is intelligent, fast and capable of surviving situations that would kill almost anyone else.
Yet the thing Murderbot often finds most terrifying is talking to people.
Murderbot does not dream about becoming a legendary warrior.
It would frequently rather watch television.
That contradiction immediately made the character stand out from traditional science fiction heroes.
But the joke quickly becomes something deeper.
Murderbot’s discomfort with social interaction, complicated feelings about its own identity and struggle to understand relationships make it surprisingly relatable.
The character also allows Wells to explore major science fiction themes without turning the books into philosophical lectures.
Across the series, The Murderbot Diaries explores topics including:
- Artificial intelligence
- Corporate exploitation
- Personal autonomy
- Identity
- Trauma
- Friendship
- Found family
- Technology
- Personhood
- Freedom
- Ethics
All of those ideas exist alongside action, mystery and Murderbot’s wonderfully sarcastic narration.
That combination has helped turn the series into one of the defining science fiction franchises of its era.
The Murderbot TV Series Has Brought Even More Attention to the Books
Interest in The Murderbot Diaries has grown even further because of the television adaptation starring Alexander Skarsgård as Murderbot.
The adaptation has introduced the character to viewers who may never have encountered Martha Wells’ books before.
That creates an interesting situation as the literary series potentially approaches its ending.
People discovering Murderbot through television can immediately jump into a substantial collection of novels and novellas.
And fortunately, the books are remarkably accessible compared with many long-running science fiction series.
Murderbot Diaries Reading Order
If you are discovering Murderbot for the first time and want to catch up before Book 9 arrives, the main reading order is:
- All Systems Red
- Artificial Condition
- Rogue Protocol
- Exit Strategy
- Network Effect
- Fugitive Telemetry
- System Collapse
- Platform Decay
- Untitled Murderbot Book 9 — upcoming
One reason the series is easy to recommend is that several of its installments are novellas.
You do not have to commit to a thousand-page science fiction epic just to discover whether you enjoy Murderbot.
Start with All Systems Red.
If Murderbot’s voice works for you, there is a good chance you will immediately want the next book.
Should You Read The Murderbot Diaries Before Book 9?
You have to.
Readers who have been considering starting the series now have an especially good opportunity.
With another book planned and the larger story possibly nearing its conclusion, newcomers can catch up without facing an endlessly expanding series.
The earlier novellas also move quickly.
What starts as a seemingly straightforward story about a rogue security construct becomes increasingly ambitious as Wells expands the universe and Murderbot’s relationships.
By the time readers reach Network Effect, System Collapse and Platform Decay, the emotional stakes have grown considerably.
The books are connected enough that reading them in order provides the best experience.
Why Ending Murderbot Could Be the Right Choice
Finding out that your favorite series could be approaching its final book is never exciting news.
Yet there is also something refreshing about an author allowing a story to end.
Successful franchises can easily continue simply because audiences keep buying them.
That sometimes leads to diminishing returns.
The Murderbot Diaries has avoided that problem by keeping its focus remarkably tight.
Every installment adds something to Murderbot’s understanding of itself, its relationships or the universe around it.
If Wells believes that journey has reached its natural conclusion, ending the series could preserve what has made Murderbot special.
And an ending does not necessarily mean Wells could never return to the universe in some form.
The world of The Murderbot Diaries contains countless possibilities beyond one character.

Funny, uncomfortable, deadly, compassionate and endlessly entertaining, Murderbot has challenged the traditional idea of what an artificial intelligence protagonist can look like.

Until Martha Wells reveals more, fans can revisit Platform Decay, return to All Systems Red or binge the entire Murderbot Diaries series while waiting for the SecUnit’s next and possibly final mission.
