In a corporate-dominated spacefaring future, planetary missions must be approved and supplied by the Company. Exploratory teams are accompanied by Company-supplied security androids, for their own safety. But in a society where contracts are awarded to the lowest bidder, safety isn’t a primary concern. On a distant planet, a team of scientists are conducting surface tests, shadowed by their Company-supplied ‘droid—a self-aware SecUnit that has hacked its own governor module, and refers to itself (though never out loud) as “Murderbot.”

It has a dark past—one in which a number of humans were killed. A past that caused it to christen itself “Murderbot”. But it has only vague memories of the massacre that spawned that title, and it wants to know more. Teaming up with a Research Transport vessel named ART (you don’t want to know what the “A” stands for), Murderbot heads to the mining facility where it went rogue. What it discovers will forever change the way it thinks.

Murderbot wasn’t programmed to care. So, its decision to help the only human who ever showed it respect must be a system glitch, right? Having traveled the width of the galaxy to unearth details of its own murderous transgressions, as well as those of the GrayCris Corporation, Murderbot is heading home to help Dr. Mensah—its former owner (protector? friend?)—submit evidence that could prevent GrayCris from destroying more colonists in its never-ending quest for profit. But who’s going to believe a SecUnit gone rogue? And what will become of it when it’s caught?

Sci-fi’s favorite antisocial A.I. is back on a mission. The case against the too-big-to-fail GrayCris Corporation is floundering, and more importantly, authorities are beginning to ask more questions about where Dr. Mensah's SecUnit is. And Murderbot would rather those questions went away. For good.

No, I didn't kill the dead human. If I had, I wouldn't dump the body in the station mall. When Murderbot discovers a dead body on Preservation Station, it knows it is going to have to assist station security to determine who the body is (was), how they were killed (that should be relatively straightforward, at least), and why (because apparently that matters to a lot of people—who knew?) Yes, the unthinkable is about to happen: Murderbot must voluntarily speak to humans! Again!
