I think that is a new and interesting protagonist tbh. So many are heros or have to develop into heroism. It’s refreshing to just have someone who explicitly doesn’t save the world or similar stakes.
If you enjoyed Murderbot, take that as a recommendation, although it is less sci-fi and more historical fiction.
Murderbot is not that. What you see of them is as genuine as their perspective can be. Murderbot may be snarky, but it doesn't have the same braggadocious air, and I do think that changes the character and story significantly. And if you're a similar kind of neuro-atypical then it can be a refreshing bit of heroic representation.
I will give Sixteen Ways some credit though - at least it ended. I don't particularly like the ending, but it is one. Murderbot falls off hard by the time the series gets to full length novels.
