Sci-Fi's favorite antisocial AI 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.

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 vessal named ART, Murderbot heads to the mining facility where it went rogue. What it discovers will forever change the way it thinks ...

Assisting Preservation Station security when he discovers a murdered body on the premises, Murderbot reluctantly speaks to humans to help identify the victim and determine what happened.

When Murderbot's human associates are captured and need its help, it must choose between inertia and drastic action, in this first, full-length standalone novel about a sentient murder machine programmed for destruction.
