I guess it was the narrator/narrative voice. Tracker seemed to quip a bit too much, for my liking anyway. This undermined the seriousness of some of the scenes for me and made it difficult to see what happened as important. Also, while the book is written in first person, Tracker mostly seemed to tell what had happened. I know this is because he’s telling the story to the inquisitor, but this placed what happened to him (Tracker) at a remove and made it hard for me to feel close to his character. I think the writer may have done this purposely, because the story is so violent, but this didn’t work for me.
