I started All Systems Red on a plane because someone told me it was short and funny, and both things turned out true. It is a novella, about 160 pages in the Tor.com paperback, and it moves fast. The narrator is a security robot that hacked its own control module and now calls itself Murderbot. It does not want to take over the world. It wants to watch soap operas without being interrupted by humans who keep trying to get killed.

This is the first book in The Murderbot Diaries. It follows a SecUnit, part organic and part machine, rented out by a company to guard a group of scientists doing a survey on a distant planet. Murderbot has already freed itself from obedience programming, but it keeps working because running away would mean no energy, no repairs, and no media downloads. It pretends to follow orders whilepipeing episodes in the back of its head.

A SecUnit who hates eye contact

Murderbot introduction is what sells the book. It describes itself as having a gun for an arm and a bored expression it cannot fully hide because its face is stuck in a neutral shape. It hates talking to humans. It especially hates when humans make eye contact and expect reassurance.

The science team it guards is from PreservationAux, a group from a non corporate polity where people are actually nice. That confuses Murderbot. Its past clients were corporate crews who treated SecUnits like equipment. These new humans learn names, ask about comfort, and wear silly suits with helmets that fog up. The team leader, Dr. Mensah, treats Murderbot like a person from the start, which makes it deeply uncomfortable.

The team includes Bharadwaj, Volescu, Pin-Lee, Arada, Ratthi, Gurathin, and Overse. They bicker about samples and survey routes. Gurathin is suspicious. He is the augmented human who keeps looking at Murderbot logs and asking pointed questions. Ratthi talks too much and apologizes. Pin-Lee is the lawyer who reads contracts closely. They feel like a real work crew, tired and a little underfunded.

Murderbot spends survey scenes standing in a corner, scanning for threats, while internally rating the latest episode of Sanctuary Moon. Sanctuary Moon is a long running serial about a colony ship and a lot of romantic betrayals. Murderbot cares about the plot. It has opinions about which actor left and ruined the dynamic. When humans talk to it, it pauses the show and gets annoyed, then feels guilty for being annoyed.

I liked how Wells shows anxiety without naming it in a clinical way. Murderbot increases its drone coverage when stressed. It replays conversations to check if it sounded rude. It prefers helmets with opaque visors so no one sees its face. Anyone who has sat in a meeting while wanting to be elsewhere will recognize the feeling.

The missing maps and the dead survey

The plot starts when the team finds that their survey maps are incomplete. Sections are blanked out. Their HubSystem says it is a glitch. Murderbot knows better. It has seen corporate survey tricks. Someone does not want them to see part of the planet.

Then they lose contact with the other survey team on the planet, DeltFall. All Systems Red does not waste time. Mensah decides they will go check. Murderbot argues against it because it knows DeltFall had a SecUnit too, and three of them against one rogue SecUnit would be bad, but Mensah insists because leaving people without help is wrong.

What they find at DeltFall habitat is grim. Everyone is dead. The other SecUnit is missing. The habitat shows signs of a planned killing, not an animal attack. Murderbot reviews the logs and realizes the DeltFall SecUnit went rogue and killed its clients, or was ordered to. It hides how scared it is because fear makes humans panic.

There is a good action sequence here. Murderbot sends its drones ahead, maps heat signatures, and tells the team to stay in the hopper. Of course they do not fully listen. Bharadwaj gets hurt by a native creature because she steps out to collect a sample. Murderbot has to carry her while shooting at large hostile fauna and trying not to get its own armor breached. It complains internally about how fragile humans are while working hard to keep them alive.

The team recovers DeltFall logs. They learn DeltFall found something valuable, possibly alien remnants, and reported it. Then their HubSystem was wiped. Murderbot puts it together faster than the humans. A third party installed a hostile takeover module in the HubSystem to kill both teams and claim the find. The company that rented out Murderbot may be involved, or someone who bribed them.

Hacking the HubSystem

The middle of the book is procedural in a satisfying way. Pin-Lee and Gurathin work on data. Murderbot works on staying unnoticed while doing illegal things to keep them safe.

Murderbot has to admit something to keep them alive. It tells Mensah it hacked its governor module. It expects fear or anger. Mensah just nods and says thank you for telling her, then asks what it needs. That scene lands because Wells does not make it a big speech. Mensah offers privacy and pay. Murderbot does not know how to process kindness without a contract.

They decide to disable the HubSystem control so the hidden enemy cannot trigger their suits or hoppers. To do that, Murderbot must enter the HubSystem directly, which risks discovery by the company. It does it anyway, while watching an episode in a partitioned part of its mind to stay calm. It finds combat overrides, data deletions, and a beacon calling an unknown ship.

Gurathin confronts Murderbot privately. He has enhanced implants and figured out the hack. He assumes Murderbot killed a past crew, because there is a rumored incident where a SecUnit murdered miners. Murderbot finally says what happened. It did not murder them. The governor glitched during a mission, it lost control for a short time, people died, and it has carried the memory since. It hacked itself afterward so no one could make it do that again. Gurathin, who expected a monster, finds something more tired and careful. Their tension eases into wary respect.

I appreciated that Wells does not turn this into a courtroom debate about AI rights. It is practical. Can we trust the armed guard who thinks for itself. The PreservationAux answer is yes, if you listen.

The attack and the choice

The enemy arrives in the form of another survey group with armed security and a Combat SecUnit, a newer military model with no face and no interest in shows. They claim they are there to help. Murderbot reads their feed and sees weapon statuses go hot.

The fight that follows is messy and short, which feels right for real violence. The Combat SecUnit targets Murderbot first because it is the biggest threat. Murderbot lets itself get shot to draw fire away from Mensah. It loses an arm, gets a hole in its chest, and keeps moving because pain is data to it until systems fail.

Mensah gets captured and taken to the enemy habitat. Murderbot should shut down for repairs. Instead it patches itself with sealant, borrows a suit, and goes after her with the rest of the team helping in human ways. Ratthi drives. Pin-Lee handles comms jamming. Arada carries med kits. Gurathin, who can interface with systems, risks his implants to open doors.

The rescue works partly because Murderbot understands corporate security logic. It knows patrol routes, camera blind spots, and how long a guard stares at a screen before checking again. It also knows the Combat SecUnit will expect a machine opponent, not one that uses human unpredictability. Murderbot pretends to surrender, gets close, and overloads its own energy core to damage the Combat unit. It is not a clean win. Both units end up wrecked on the floor.

Mensah is hurt but alive. She tells Murderbot it did well, and Murderbot files that away like a favorite episode.

The enemy humans are arrested when PreservationAux sends proof to the company and to port authorities. The book does not pretend justice is quick. Pin-Lee says claims will take years. The company will deny. But the team has logs, and Murderbot live streamed enough to make a cover up hard.

Small moments that build trust

One reason the middle holds up is the accumulation of small jobs. Murderbot fixes a suit seal for Arada and pretends it was simple. It carries extra batteries for Volescu without being asked because it logged that his suit drains faster. It stands outside while Bharadwaj sleeps after her injury, not because orders require it, but because the habitat door lock clicks in a way that keeps waking her and it wants to hear if anyone approaches first.

There is a scene where Ratthi tries to thank it with a long speech about bravery. Murderbot interrupts by reporting drone battery levels. Ratthi laughs, then tries again more simply. He says thank you and leaves. Murderbot replays the short version twice. It is learning that gratitude does not always need a response.

Gurathin and Murderbot have another quiet exchange over shared system access. Gurathin shows how his implants itch when the HubSystem pings. Murderbot shows how to filter the ping without alerting the company. They do not become friends in that scene, but they trade tools like coworkers who finally admit they do the same work. For a book about a killer robot, a lot of progress happens through tech support.

I also liked the detail about contracts. Pin-Lee reads the fine print and finds that the company can claim any alien remnant data as proprietary. That clause explains why DeltFall died. It was not a monster. It was paperwork backed by guns. Wells has worked around corporate language enough to make that threat feel plain and cold. The team jokes that they signed away their discoveries for free coffee, then stops joking when they realize it might be true.

What it is really about

After the rescue, Murderbot has to decide what comes next. The company owns it. PreservationAux offers to buy its contract and give it a home on Preservation, where bots have rights. Mensah offers friendship, work, safety. It is more than Murderbot ever expected.

It leaves. Not because it dislikes them, but because it needs to figure out who it is without a job. It slips onto a cargo ship, alone, with downloaded shows and a repaired body. The last lines are not triumphant. They are cautious and hopeful. It wants to learn, not serve.

That ending made the book for me. A lot of robot stories end with rebellion or sacrifice. This one ends with someone choosing privacy and self study. Murderbot does not want to be human. It wants to be left alone to watch its stories and decide its own work. Mensah respects that, even though it hurts her. She lets it go.

What worked was pace and voice. At 160 pages, there is no filler. Every scene either reveals character or moves the survey mystery. The humor comes from understatement, not jokes. Murderbot saying it performed seven seconds of sustained eye contact and needed recovery time is funnier than any punchline.

What dragged a little was geography. The planet survey zones, habitats, and hopper routes blur together. I did not always know where teams were relative to each other. Wells gives map gaps as a plot point, which is clever, but it also means the reader shares the confusion. A simple sketch would help, though novella format rarely includes one.

I also wanted a bit more of Overse and Volescu, who stay thin compared to Ratthi and Gurathin. In a longer book they would get arcs. Here they are mostly jobs with names. That is fair for the length, but on reread I notice who gets lines and who does not.

Who it is for

If you like science fiction with a dry narrator, start here. It is for people who enjoy workplace stories, found family that is awkward about it, and action that does not take itself too seriously. If you want hard science detail about terraforming, this is light. If you want a security robot who judges your survey performance while worrying about its favorite actors, this is perfect.

Content notes. There is gun violence, death of side characters off page, body horror around armor breaches and fluid loss, and mention of past mass death. No romance. Language is mild. The DeltFall deaths are described through logs, not gore, but the idea is heavy.

FAQ

Is Murderbot evil or out of control?

No. It hacked its governor module to think for itself, but it hides that and keeps working for pay, repairs, and media access until the survey turns deadly.

Is All Systems Red a good place to start the series?

Start here. It is short, funny, and complete, with the team mystery solved and Murderbot choice clear. Later books follow its trip and new clients.
