System Collapse is science fiction, part of Wells' Murderbot Diaries series. I bought my copy new.
Review:
This takes place immediately following the events in Network Effect - as others have said, I highly recommend reading or rereading Network Effect just before digging into this book, because there's a lot that probably won't make sense otherwise. In a way, System Collapse feels like bonus content for Network Effect.
Murderbot, ART's crew, and the Preservation humans are still on the planet and having to deal with occasional "alien contamination" complications, but everyone's biggest concern is making sure that the colonists have the knowledge and opportunity to decide for themselves what their next steps are. This means somehow keeping the Barish-Estranza folks from convincing them to sign their rights away and become indentured slaves.
