“Having someone else support your bad decision feels kind of good.

After volunteering to run a rescue mission, Murderbot realizes that it will have to spend significant time with a bunch of humans it doesn’t know.

Including human children. Ugh.

This may well call for… eye contact!

(Emotion check: Oh, for f—)”

Series Info/Source: This is 8th book The Murderbot Diaries. I got an eGalley of this from NetGalley to review.

Thoughts: The last book in the Murderbot Diaries was published in Nov of 2023, so it’s been quite awhile since we’ve seen a new Murderbot book. As a result the beginning of this book, which jumps straight into action, is incredibly confusing. As the story continues, we do get clarification about what is going on, but I was nearly 30% of the way in before I figured out why Murderbot was doing what it was doing and why it was where it was.

The beginning of this book has Murderbot and Three infiltrating a massive rotating space station shaped like a torus, things go sideways when Barish-Estranza troops show up. I was quite sure why Murderbot and Three were infiltrating this space station until much further into the story. You are plopped straight into the action, which was a bit confusing.

Once I got about 40% of the way in, I was fully engaged in the story, understood what Murderbot was doing, and didn’t want to put the story down. However, that first third was pretty clunky and confusing. If you are going to take years between publishing books in a series, you have to give at least a few sentences of recap at the beginning. Not all readers go back and re-read the whole series before the next book or even have access to the previous books in the series.

I enjoyed Murderbot’s normal sardonic comments and also enjoyed the new “emotion check” functions. I didn’t feel like Murderbot grew much as a character in this book. This story felt very much like filler to me and was a bit disappointing. I didn’t feel like it progressed Preservation’s story much or really progressed any larger storyline at all. It was a very compact and separate story from the rest of the series. Additionally, the way the book wrapped up was incredibly abrupt. I was left feeling like, uh, okay I guess the book’s done then.

I would love to feel like that is a broader story arc here that is making progress, but at this point, I think we are just reading about instances in Murderbot’s existence. Which is fine, I guess. I just really loved where some of the previous books were going, and this feels so much like filler to me.

My Summary (4/5): Overall I enjoyed revisiting Murderbot and this world. I was disappointed at how confusing the first part of the book was and at how abruptly the story ended. The second half was action-packed, and the book was very hard to put down for that portion. All of this left me a bit confused about how to rate this book. The first part 3 stars, the middle to end portion 5 stars, then the end 3 stars…so I settled on 4 stars. I will definitely continue to read this series but feel like this book wasn’t as good as come of the previous books.
