Summary
Two years after hacking its governor module, SecUnit003/"Three"/"Theo" is enrolled at the Pan-System University of Mihira & New Tideland because... reasons. It would, honestly, much rather be riding wormholes and liberating constructs and helping its friends aboard Perihelion, but it has a mission and needs to see it through.
It also has several humans students that it is trying to be friends with for... reasons.
And, if those reasons involve it having limited feed access, disabling its weaponry, and generally having to refute its basic function to try and accomplish this mission then...
[MISSION PARAMETER LOCK]
...Then, it's just going to have to grit its teeth and bear it.

Summary
“Perhaps constructs are immune,” Three said and I felt a ripple of fear through my organics. I had said similar to 2.0 right before finding out I was ‘in network'.
“ART, initiate quarantine protocol,” I said. I hoped it was not too late. I suspected it definitely was.

Summary
"It's wrong to think of a construct as half bot, half human. It makes it sound like the halves are discrete, like the bot half should want to obey orders and do its job and the human half should want to protect itself and get the hell out of here. As opposed to the reality, which was that I was one whole confused entity, with no idea what I wanted to do."
Six months into its new life aboard the Perihelion, Murderbot has settled into a comfortably aloof routine with its mutual administrative assistant, ART. Then a new crew member arrives and a survey mission goes catastrophically wrong, uncovering a corporate conspiracy that hits closer to home than anyone expected. As events spiral out of control, a harrowing mystery, the indifferent cruelty of the Corporation Rim and (ugh) its own inconvenient emotions all conspire to force Murderbot to reevaluate what it really wants from the universe and what it means to live in a world of bots and humans when you're neither.

Summary
If you're going to make a tunnel, make a floor. There shouldn't be dirt in tunnels. And there shouldn't be evil microfauna in the dirt, but if there is, then there should definitely be a floor to seal off that dirt completely.
Murderbot and Secunit 3 have a bad day.

Summary
It's not like they were rigging this surgery with a pen-knife and a shoe-string, they had a friendly MedSystem to help out, but deactivating Three's dataport without ART's help was never going to be easy.
And it was going to be mortifying.

Summary
SecUnit Three has been free for a very short time and is not doing well. As it tries to navigate the first personal request of its life, it makes lists. The request is more emotionally catastrophic than it realized, and there is probably a very, very good reason why Murderbot initially said no…

Summary
SecUnit 3 experiences its first 100 hours without a governor module.
The first 10 hours were spent recovering 1.0 from alien hostiles. Those turn out to have been the easy hours. At least Three had protocol to cover some of that situation. Now SecUnits 1 and 2 are inoperative, 1.0 has blocked it, Perihelion terrifies it, and Three is alone.

Summary
People get attached to things, their clothes, their vehicles, that funny stone they found on the beach as a child. Sometimes even their SecUnits. To the SecUnit in question this is an unsettling new process.

Summary
It is with great relief that I exit the wormhole into the home space of the Pan System Alliance. Familiar neutrinos brush against my hull, lighting up my sensor array in a comforting way. I immediately receive three pings from members of my cohort who are in range. I return the pings merely to be polite, but ignore any further initiation of conversation. I am really not in the mood to be interrogated about my recent mishap.

When Murderbot is damaged in a mission-gone-sideways, it and Three back-track to a ComfortUnit brothel where the governor-module override code has already done its job and there's a SecUnit repair cubicle it can sneak into.
While it's busy getting its repairs done, Three gets busy... getting busy with a ComfortUnit who thinks SecUnit physiology is bullshit.

Summary
Murderbot's new client is... complicated. She's also an old friend of Ayda Mensah, Murderbot's favorite human.
The mission seems straightforward at first. But keeping Dr. Silnot alive will also turn out to be... complicated.
