The titular “Murderbot” is a robot charged with the defence of a survey expedition on an alien planet. The murderbot has hacked her (his?) governor module and is secretly no longer constrained by her programming. Nevertheless, in a crisis situation, she helps her survey expedition and wins their trust.
This novella is an interesting take on sentient created life. The murderbot, telling the story in the first person, has a humorous narration style, with dry wit used to lay bare questions of purpose in life, and the need for companionship, or not. Unfortunately, the story itself sometimes stumbles into tediousness due to a clumsy use of contrived technological constraints used to anchor plot points.
