Few modern science fiction series have captured readers’ imaginations quite like The Murderbot Diaries. Ever since All Systems Red won the Hugo, Nebula, and Locus Awards in 2018, Martha Wells’ sarcastic, socially anxious SecUnit has become one of the most beloved protagonists in speculative fiction.
With the release of Platform Decay, fans are already asking the inevitable question:
When will the next Murderbot book come out?
While Martha Wells hasn’t officially announced a publication date for Book 9, she has shared some intriguing comments about the future of the series that give readers plenty to discuss. Here’s everything we know.
Is Another Murderbot Book Confirmed?
Yes.
Although there is no official title or release date yet, Martha Wells has confirmed that she plans to write another Murderbot novel. More importantly, she has suggested that Book 9 may serve as the conclusion of the series, though nothing has been finalized.
That means fans can look forward to at least one more adventure with their favorite security unit.
When Could Murderbot Book 9 Be Released?
At the time of writing, Tor Books has not announced a release date for Book 9.
However, looking at Martha Wells’ publishing history provides some clues.
Recent releases include:
- System Collapse (2023)
- Platform Decay (May 5, 2026)
There was nearly a three-year gap between these two installments, though part of that delay came as Wells balanced other projects, including her fantasy novels and involvement surrounding the Apple TV+ adaptation.
If she follows a similar timeline, readers could reasonably expect Book 9 sometime in 2028, although this remains speculation until Tor Books makes an official announcement.
Why Fans Think Book 9 Could Be the Final Murderbot Story
One of the biggest revelations came from Martha Wells herself.
In a recent interview, Wells explained that she’s begun thinking seriously about how Murderbot’s journey should end. She indicated that Book 9 may be the final installment, though she also emphasized that she wants to conclude the story naturally rather than stretching it indefinitely.
For many fans, that’s bittersweet news.
The Murderbot Diaries has remained remarkably consistent across eight books, avoiding the decline that affects many long-running series. Rather than continuing simply because it’s successful, Wells appears committed to ending the story on her own terms.
That’s often the hallmark of great storytelling.
Platform Decay Sets Up What’s Next
Released on May 5, 2026, Platform Decay continues Murderbot’s journey after the events of System Collapse. The novel once again mixes high-stakes action with the dry humor and emotional introspection that have defined the series.
Without venturing into major spoilers, the latest installment continues exploring several questions that have lingered throughout the series:
- What does freedom truly mean for an artificial intelligence?
- Can Murderbot ever stop running?
- What responsibilities come with independence?
- How much humanity has Murderbot developed?
These questions feel increasingly important as the series approaches what could be its final chapter.
Why Murderbot Has Become One of Science Fiction’s Greatest Characters
It’s difficult to overstate how influential Murderbot has become.
Unlike many science fiction protagonists, Murderbot isn’t driven by heroism or glory.
Instead, it wants something surprisingly relatable:
To be left alone.
Preferably while binge-watching thousands of hours of entertainment media.
That simple premise evolves into something much deeper. Over eight books, readers watch Murderbot slowly build relationships, confront trauma, and discover what autonomy actually means.
Its anxiety around human interaction has resonated with countless readers, while its sarcastic internal narration remains some of the funniest writing in modern science fiction.
The series also tackles surprisingly complex topics:
- Corporate exploitation
- Artificial intelligence
- Identity
- Trauma recovery
- Found family
- Personal autonomy
- Ethics of technology
Despite these heavy themes, the books never lose their sense of adventure or humor.
The Apple TV+ Series Has Introduced Murderbot to New Fans
Interest in the books has only grown thanks to the Apple TV+ adaptation starring Alexander Skarsgård.
The television series has introduced countless new readers to Martha Wells’ work, leading many to immediately pick up All Systems Red after finishing the first season.
Fortunately, Wells has made it clear that the books and television adaptation will remain separate continuities, allowing each version to tell its own story without forcing changes onto the novels.
That should reassure longtime readers who appreciate the unique voice and tone of the original books.
What Could Book 9 Be About?
Since no synopsis has been released, everything remains speculation.
However, several possibilities seem likely.
A Final Showdown with Corporate Powers
Barish-Estranza has served as one of the primary antagonistic forces throughout the series.
Many readers expect Murderbot’s final adventure to involve a larger confrontation with the corporations responsible for so much suffering.
More Growth for Murderbot
One of the defining strengths of the series has been Murderbot’s gradual emotional development.
Rather than undergoing sudden transformations, each book nudges the character forward in believable ways.
Book 9 could complete that arc while remaining true to Murderbot’s personality.
The Future of Free SecUnits
Another lingering question concerns other liberated constructs.
What happens to artificial intelligences once they’re free?
It’s a question the series has explored repeatedly, and one that could become central to the finale.
Why Martha Wells Ending the Series Could Be the Right Decision
Fans naturally never want a favorite series to end.
But there’s something admirable about an author recognizing when a story has reached its natural conclusion.
Many beloved franchises continue well beyond their strongest ideas.
The Murderbot Diaries has largely avoided that trap.
Each installment has maintained the sharp humor, emotional intelligence, and inventive worldbuilding that made readers fall in love with the series in the first place.
If Book 9 truly is the ending, there’s reason to believe Wells will deliver a satisfying conclusion.
Should You Start Reading Murderbot Now?
Absolutely.
One of the biggest advantages of the series is its accessibility.
Most entries are novellas that can easily be finished in a single afternoon, making the entire series far less intimidating than many sprawling science fiction sagas.
The recommended reading order is:
- All Systems Red
- Artificial Condition
- Rogue Protocol
- Exit Strategy
- Network Effect
- Fugitive Telemetry
- System Collapse
- Platform Decay
Together, they form one of the strongest science fiction series of the past decade.
Final Thoughts
While fans will have to wait a little longer for official news, one thing is certain:
Another Murderbot book is coming.
Martha Wells has confirmed that Book 9 is in her plans, even if its publication date remains unknown. The biggest question now isn’t whether another novel will arrive—it’s whether that book will truly mark the end of one of the greatest science fiction series of the modern era.
Until then, readers can revisit Platform Decay and the rest of The Murderbot Diaries, a series that has redefined what an AI protagonist can be. Funny, deeply human, emotionally resonant, and endlessly entertaining, Murderbot has earned its place among the most unforgettable characters in contemporary science fiction.
Whether Book 9 arrives in 2028 or sooner, it will undoubtedly be one of the most anticipated sci-fi releases of the decade.
