This seventh Murderbot story is a direct sequel, a part 2 even, to Network Effect, which was not actually the previous book published. So if it's been a couple years since you read Network Effect, it's worth doing a quick reread before starting this one as there are a lot of references to the events in that book which will be hard to keep track of unless it's fairly fresh in your memory. Or at least read a plot summary somewhere.

That said, Network Effect did seem to leave a lot of questions unanswered at the end, so getting a part 2 is wonderful and learning a bit more about ART and the organization ART is part of were an extra treat. I ended this book wanting an entire side series about Three and where they end up. Another satisfying Murderbot treat!
