This one made me cry at the ending as Muderbot rebuilds its memory and grapples with human emotions, and the true freedom it's friends give it, because they recognise it as a fully sentient being that happens to be partially robotic.

Probably the most human set of experiences I've read in fiction.

Murderbot finds out it's friends are in trouble. Mensa is caught by GrayCris, and it sets out to help. Of course mayhem ensues, but that last chapter hits you hard in the gut with emotion.

Highly recommended.
