The 8th MurderBot novel by Martha Wells is another entry into this fine series of books at a security unit that isn't all machine, and also isn't all human. It has organic parts and looks mostly like a human. And yet it's pure killing machine, designed to keep it's assets alive, get them out of dangerous situations in a science fiction future where corporations are at war with each other, and do dastardly thing. There's an Apple tv show that is okay, based on it. It kind of shows that a minimalist non-human narrator can run an action novel. Many of the 8 are pretty short, which is good. Does it's constant risk assessment tell us about our present? Does it's ruthless focus on saving individual lives tell us something?
