I've been meaning to read this for years now, and it's finally reached the top of the to-read pile. It's got a fantastic, sardonic tone, and I don't know what inspired the story, but I like to think of that little rover on Mars, and how it sings birthday songs and has a whole lot of people emotionally invested in it. 

On a technical level, one of the things that I noted and admired here was a great way of dealing with handwavium. Any time the story approaches something scientific - such as how emergency beacons interact with wormholes - Murderbot is all "I haven't downloaded this information and so I don't know. Also, I don't care." As a reader who often finds extraneous and overly technical worldbuilding to be somewhat tedious, a great big fat hooray to that. We don't need it, and I don't care either. I want emotion, and - horrified as it may be to hear it - Murderbot doesn't skimp on that.
