While the page count is about the same as the previous two novellas, this one feels really short and thin, largely because there's only a very short and mostly uneventful ship ride and then a single main story of hijinks, and for most of that Murderbot is an observer.
The facility where most of the time is spent is given only a desultory description, often I have to piece together how it looks and fits together when something is introduced, like windows along the service tunnels. I still have very little idea of what the planet surface is like. There's some "haunted spaceship" atmosphere for a bit, and then reality sets in and Murderbot just has to solve problems, i.e. do some hacking and then very destructive combat.
A bot named Miki is somewhat interesting, as the exact opposite of Murderbot in every way. The humans in this are, as always, dumb, slow, and annoying, whether helpful or antagonistic. It's the reverse of how most SF treats robotics, where the people are interesting and the bots are all the same.
But I can't say this one's that great, full price is excessive on a novella that doesn't deliver. ★★★½☆
Next novella should finish this story, and I'd hope after that Martha writes full novels in the setting.
