Absolutely thrilled to get another installment of Murderbot adventures, and even more so that this one includes Murderbot interacting with children!
I honestly expected (and wanted) more interactions with children from it, but most of the people in this book are adults.

The story takes place not too long after System Collapse , thus extending on the plotline that first started in Network Effect . It involves both familiar and new faces, as well as people that have been mentioned before but never appeared on-page thus far.
It takes places on an unfamiliar, massive space station, where Murderbot is sent in a mission.

My favourite recurring character was Three, who has definitely not gotten enough attention in System Collapse! To be honest, even now in Platform Decay it doesn't get enough attention, but I'll take what I can get.

That is maybe also my biggest gripe with the book - it just doesn't go as in depth in many of the areas where I wanted it to. Specifically, the character dynamics. The Murderbot Diaries are such an intensely character-driven series, but I have noticed before how the books (especially the last few) seem to almost shy away from showing us any details of Murderbot casually interacting with others (or other characters with each other). To a certain extend, that makes sense, as Murderbot is famously anti-social (or pretends to be). But it's starting to frustrate me a little bit, especially here, where two of the most prominent characters in the series, and the two people Murderbot itself is the most attached to, get one or two lines in the last 2 pages at most, not even enough to be considered a dialogue.

I also found the overall tension arc of this book a bit confusing - there is a huge confrontation 60-70% in the book that is very detailed, high-stakes and emotional. Then anything after that is abbreviated. A lot of the book, Murderbot and its companions spend travelling, and while the previous stops were all described in detail, the book then just skims over several more stops before going into the finale. And that finale pales significantly in comparison to the earlier confrontation, and ends super inconclusively. The book then jumps straight into a very (emotionally) unsatisfying ending.

I am aware that my personal frustration with the lack of epilogue to round out my emotional investment in the book heavily tinges how I feel about it, but I do think that even disregarding the ending, this is one of the weakest installments in the series. It has wonderful moments, the typical humor, an emotional punch, and is very intrinsically Murderbot - but the way it is plotted and structured isn't as cohesive as the other books, and it feels unbalanced in some parts.

I received an ARC and reviewed honestly and voluntarily.

Platform Decay is the next Murderbot adventure, a tale about a SecUnit who volunteers for a rescue mission and must face the social terror of spending significant time with humans, including children.

This eighth instalment in Martha Wells’s Murderbot Diaries is scheduled from Tor Books on May 5, 2026, and it continues the chronicle of a sardonic, reluctant guardian who prefers media to eye contact, yet keeps choosing to help people anyway. Murderbot signs up for a rescue that will force more close interactions with humans than usual, and that premise alone promises the mixture of wry humor and tense action.

What I’m most excited about will be to watch Murderbot negotiate the impossible, which is emotional labor with children and strangers, while still hiding behind snark and streaming. The book’s listed page count and publisher details confirm it is a full, return installment rather than a short vignette, so I anticipate more sustained character work and broadened stakes. My hope is that Wells gives Murderbot scenes that test its trust and tether it to people who matter in new ways, with enough action to satisfy fans and enough interiority to make those actions matter.

This genuinely feels like one of the best installments in this series. There is so much emotional payoff for things we’ve been building towards. We got to meet more of Mensah’s family and let me tell you, one of them is a hoot and the other has a homicidal eyelid twitch. They’re perfect.

I can’t wait to reread this when the audiobook drops.

Super looking forward to this. Since reading MB diaries I have had a blast getting into drawing again, trying out fictional writing, animating again, exploring my own presentation, making new friends and having a safe fictional avenue to discuss the stolen generation and how lateral violence can present in systematically oppressed people.

From the summary I am selfishly hoping we see Murderbot connecting with Three and other constructs. I am feeling hopeful after its tentative overtures in System Collapse, granted they were during conflict. So I am really keen to see how it socialises with its own kind outside of that.

I hope there's a special illustrated edition by Jaime Jones again. I missed out on System Collapse so if there is one for Platform Decay I will sign up to buy that so fast.

Murderbot is adjusting to life with its humans learning to trust it. Dr Mensah has asked Murderbot to rescue several family members, which it will of course do because Dr Mensah and her family is its people. The plan goes awry (because no amount of careful planning would have had it predict Leonide of Barish-Estranza would be there) and due to circumstances well outside of its control, Murderbot is now responsible for rescuing more people it doesn't know. And they are juveniles. Murderbot knows its duty, though, and with its newly installed mental health module, maybe it will get though the mission er, emotionally in tact, too.

A new Murderbot book is worth dropping everything else to read, to see what adventure Martha Wells will take us on. Platform Decay is a short novel/long novella and takes place after the events of System Collapse. The plot arc feels closer to a novella in structure, and reads fast paced because of it. This is actually the first Murderbot I've read with my eyes since All Systems Red in 2020, and all of my rereads have been via audio since, but I found myself really enjoying the parentheticals and side commentary from our favorite high-anxiety SecUnit.

Murderbot's mental health module provides a new influx of comic relief (and human insight) where jokes of it relying only on its media alone to get through the worst were not sufficient after its system collapse in the previous book. We read Murderbot stories for for their keen relatability to human nature and its snarky attitude, and the emotion checks tie us back to that. The emotion checks force an honesty in Murderbot and progression in character from where it was when it first hacked its governor module to realizing who its humans were to bearing the emotional burden of choice and friendship.

Thank you to Tor for an eARC. Platform Decay is out 5/5/2026.

Emotion Check : Delightful

This 8th episode of the Murderbot Diaries delivers all of the clever banter, action and dare I say...humanity?

SecUnit takes on a new rescue mission. Along for the ride is Farai and the others, but we also get some new characters that will add to Murderbot's responsibility. As always, B-E is hunting them but SecUnit and it's tech are clever enough to stay one step ahead.

I could not love Murderbot more.

thank you to NetGalley for the ARC to read and review.

This one was solid. I think Murderbot itself was more engaged with the humans, which definitely signifies some growth there. Though the actual mission felt a little like throwing spaghetti at the wall from the sheer amount of totally disconnected things that kept happening that Murderbot then had to somehow weasel its way out of without putting any of its humans in danger. The ending felt more than a little abrupt, but I suppose that’s par for the course with novellas.

I also had a hard time slotting this story into the overall timeline. I think, based on references to Amena and the existence of Three that it takes place chronologically right after the previous novella, but that wasn’t super obvious (at least without rereading that one)

I didn’t love System Collapse, the previous book. I’ve read it three times now and it seems less funny and meaningful than all the other books in the Murderbot series, and harder to follow.

So I was nervous about Platform Decay. We spend almost no time with any other characters we know – at least with any other characters we know well. The “bunch of humans it doesn’t know” referred to in the book’s blurb are relatives of Mensah. But I scolded myself for expecting Ratthi and Gurathin all the time and went with it.

Aside from new humans to deal with, and a new location, it was pretty typical Murderbot. Figuring stuff out, doing too many things at once, being sarcastic, not having enough time to watch media. The new humans are fine and cast a bit of light on Murderbot’s relationship with Mensah. (And an early reference to JollyBaby made me laugh.)

This book is definitely not a starting point for a new reader or someone who has only watched the TV series. We are in pretty deep with Murderbot at this point. I would say this was most similar to Artificial Condition, only with less ART and with Murderbot feeling more confident in its own skin.

I read an advance reader copy of Platform Decay from Netgalley.

Thank you to Tor who provided me a copy of this title though NetGalley.
Once again Wells delivers a Murderbot book that's fun, sassy, and exactly what fans come to expect from this series. It starts with Murderbot and Three infiltrating a station on a rescue mission which turns into a more complicated situation, because as usual, Murderbot has shit luck when humans are involved.
We're introduced to a few new members of Mensah's family, and they are a delight, Naja especially. She's not allowed to have a gun, and I would love to know the context surrounding that.
The story also reads like the space version of the worst airport experience ever and has an overall lighter tone from System Collapse. This is added to by the addition of Murderbot's new mental health process Emotion Check, which is so enjoyable, I can't wait to see how it's utilized in future books.
Murderbot continues to be the most relatable character I've ever read and l think fans new and old will greatly enjoy this instalment.

Low-key stakes, maximum Murderbot vibes

Platform Decay once again proves that Martha Wells could make Murderbot do something mundane for 250 pages, and I'd still read and enjoy it. 

This novella isn’t high-stakes or earth-shattering, and honestly? I didn’t mind one bit. Spending time in Murderbot’s head is the whole appeal — the dry humor, the reluctant care, the constant analysis of human weirdness.

What really struck me is how vulnerable Murderbot feels despite being the most heavily armored, heavily armed being in any given room. Wells does such a good job making that contrast feel natural — this balance of soft, anxious interiority wrapped in indestructible metal (although there is a good portion of....costume change...in this novel).

The story itself is quieter: more observation, more relationship dynamics, more internal processing than explosive action. And it works. I was fully hooked, simply because time with Murderbot is time well spent, even when the stakes are small and the character growth is incremental rather than colossal.

4.5/5 stars

Thank you @netgalley and @torbooks for the eARC!

Another good addition to the series. I enjoyed it, although I won’t call it a fave. This weirdly feels like a filler episode since SecUnit isn’t yet on mission with Art and its crew. This is a rescue mission. I was so confused in the beginning since we are thrown in with little explanation, but as well it all comes to light pretty quickly.
There were a lot of moving parts, places, hostile #s, and drones so I did get confused a few times on what exactly was happening. I think I might enjoy this one more the next time through.

But yes, I enjoyed this and as always am looking forward to the next one!

Platform Decay by Martha Wells is the eighth in the Murderbot series; it’s due out May 5, 2026. I had a copy via Netgalley. Our hero begins a rescue mission to an unusual space station–a torus circling a dead planet–with Three. After Three separates to provide a distraction (which seems like it will turn into a separate story), Murderbot proceeds with the rescue. Then it unexpectedly encounters an old enemy, which leads to a hazardous journey through an interesting series of environments, while trying to avoid security in search of a rogue Sec Unit…or more than one. The plot rollicked along and I loved how Murderbot did its job while also acknowledging and wrestling with its emotions.

A new Murderbot! This is my comfort series - one I reach for multiple times a year. I desperately needed this to be good, and it did not disappoint!

Platform Decay is charming and funny, with action that kept me on the edge of my seat. It has everything that made me fall in love with the series. Murderbot is on a mission to rescue a kidnapped family. As always, Murderbot is trying its best to keep these humans safe, even though the juveniles insist on clinging to it and the stupid station is the size of a planet and it’s new mental health module won’t stop demanding emotion checks.

The huge space station setting was genuinely interesting, and I fell in love with all the new characters. I was especially thrilled to see how Murderbot adapted to interacting with juveniles. I’m so impressed with how Wells continues to develop Murderbot as a character. Murderbot is growing and changing but is still the Murderbot we know and love. Fans will love this latest installment of The Murderbot Diaries!

I received an eARC from Tor Books. Opinions are my own.

Muderbot never disappoints. I loved seeing Murderbot deal with its trauma and I adored getting to see snapshots of Three learning how to be its own being. I did wish we got more reoccurring characters, but it was delightful to see Murderbot through the eyes of Mensah's family members. It was also lovely to see it get more comfortable with people and being seen as a valuable team member. A great follow up in the series! Left me wanting more, as always.

I love Murderbot!!!! I should’ve saved this or read closer to pub date, but I couldn’t!! And I have no regrets, except that it’s over now. (I’ll probs reread it in Graphic Audio format eventually, though).

This one starts out right in the action and you have no idea what’s going on for the first 15% or so (I thought I’d maybe missed a book??). But ofc it’s all intentional. And the payoff is great.

I can’t say too much for fear of spoilers, but the humans in this one are delightful. I love them all!!

Maybe it’s messed up, but I kind of cheer when Murderbot gets to fight/shoot people? I mean, you’re reading a review for Murderbot #8, you probably get it.

Anyway, if this series ever ends, I will cry!! (Emotion check: feeling all the feelings)

Thanks to Netgalley & Tor for the e-arc! It’s out May 2026!

Thanks to NetGalley for providing me with an Advance Reader copy of this title!

Those of us who are Murderbot fans will need no inducement to have already pre-ordered this title; any review which stated "Shenanigans Ensue" would cover the heart of the book reasonably well for such individuals.

(For those who haven't yet discovered the joy and beauty that is this series, please be advised that this is the latest volume in a series; don't start here.)

The shenanigans mentioned above include: Murderbot and Three undertaking a rescue of Mensah's family members from a Corporate station, Three absolutely having their own ideas about the agenda of the day (hint: not all SecUnits are the same), Murderbot being surprised that it isn't the center of the universe, a good look at what the folks-next-door think about Corporate goons, and how when you've only ever had a hammer, it's hard to remember to use the other tools in your new toolbox (metaphorically speaking.)

In short: it's just as awesome as all the others!

In the 8th book in her Murderbot Diaries series Wells further develops the characters and world while giving readers yet another action - and ugh emotion - packed novella. SecUnit is relieved to be off Hell Plague Planet, and on another extraction similar to Exit Strategy, only this time with more humans to save, including a complicated alliance that gives a glimpse into family dynamics in the corporation rim.

Fans of the series will be excited to welcome Three into the mix, and see it try to navigate it's own journey into autonomy, aided by a aggrieved, yet supportive, SecUnit. All-in-all yet another absolute gem of a book to add to the series.

That summary is not at all encouraging. Why does it sound like the summary for a kid's book, when this is supposed to be for adults, and this is supposed to be when "things really change" like she's promised us twice now?

How is she gonna get mad at people thinking this series is funny and cute when she's writing summaries like this? We're really expected to treat this as deathly serious when in the book she promised us would be about Murderbot finally making a real difference in the world....is this summary?

Having volunteered to run a rescue mission, Murderbot realises that it will have to spend significant time with a bunch of humans it doesn't know.

Including human children. Ugh.

This may well call for... eye contact!


Excuse me? This is the deathly serious story I'm supposed to take seriously? This is her fulfilling the promise that "things will change next book!!! Just keep shelling out more money than you'd pay for an actual novel with actual characterization, setting, and basic descriptions of the characters?

If you were holding your breath waiting for things to meaningfully progress in this story, stop holding your breath, you're gonna pass out before that ever happens.

"Things will be different in the next book!" And then this is the summary we get. Ridiculous.

Edit: Wow. The fact that Goodreads lets people leave ratings on books that they haven't read yet, because they're not even published yet, really speaks volumes. Literally giving this book a fake good rating when literally no one has read it yet, because that'll push sales on Amazon. Congrats everyone for oiling the corporate machine.
