The novel has several twists which I thought were pretty clever. The ending leaves the reader, and Unit Four, in a philosophical conundrum.

Book 4 of 4 of The Murderbot Diaries tells of the humanization of Murderbot, a weaponized cyborg that became self-aware, one stop forward by making him… care about Dr. Mensah, who is in grave danger. But is Dr. Mensah his owner or friend?

While this book could be a standalone, I would highly recommend reading the first two. This novella would make a lot more sense, and would be much more enjoyable instead of reading it as a standalone book.

The technological aspects that the author writers about are very creative, and one can see that she put in a lot of thought into them

Even though this book is short, the world building is fantastic. The vision of a future that is run by corporations, with little if any input from governments, is eerie and scary.
