From the plot alone, this novella would be a bit of perhaps cliche science fiction. What makes it both unique and compelling is that the story being told from the perspective of the "Murderbot" (hence The Murderbot Diaries), a cyborg generally treated by society as a piece of equipment.

Martha Wells's writing does a good job of showing Murderbot's personality, its particular anxieties, its relationships towards humans, and general attitudes towards life. Even if the plot is cliche, Murderbot as a character is the opposite.
