System Collapse has a great ending, possibly the best yet in Martha Wells’ wonderfully engaging Murderbot series. I emphasize that because I was a little lost at the beginning of the short novel, though that was mostly my fault. The story in System Collapse picks up immediately after the end of Network Effect, which was the second Murderbot story that I read. In the intervening two years, I read four more novellas in the series, so the setup was not fresh in my mind and had been overlaid by other stories with the same characters. In that regard though, I partly mirrored the state that SecUnit — the more friendly and more common name for Murderbot — finds itself in at the novel’s beginning. Something redacted has happened to render some of SecUnit’s memories unreliable, something that has slowed its reactions, and muddled its thinking.
SecUnit, a team of humans from Preservation, and the ship Perihelion — dubbed Asshole Research Transport, ART, by SecUnit — are all still on a planet that has proved hostile along unexpected vectors. They are still near a site of alien contamination that they narrowly escaped in Network Effect. They still want to evacuate a colony of humans who have been cut off from the larger starfaring civilization while all remain free of the contamination. And there is still a team from the Corporation Rim who also want to evacuate the colonists, but as a means of gaining indentured laborers. If they wind up killing SecUnit and company on the way to that KPI, that’s just business, right? Effective, efficient, but nothing personal. The colonists, for their part, have just encountered two groups presenting wildly different versions of the universe outside of the only world they have ever known. Should they trust either?
Then SecUnit and the humans it’s working with find out that there is potentially another settlement up near the massive engines that are terraforming the planet. Those interfere with scans, sensors and long-distance communications so thoroughly that the only way to find out for sure is to send a detachment to go and look. The group that may have settled there was a splinter and did not want to be in contact with the main colony, so they selected a location to keep themselves incommunicado. Ignoring them would leave them open to the planet’s alien contamination, which could then potentially spread beyond the planet. Not really an option, then, and most of System Collapse is about what happens when SecUnit and a small team go up to have a look-see.
