The audiobook was a pretty good choice for this book,in my opinion. It was quite light considering it's a book about serial murders; the worst parts to read were those regarding their father. there were no big plot twists that you couldn't guess, but that doesn't mean that the plot was bad. It tells me in fact that the storytelling was really good and that the characters made sense.
i find it a very nice, short story (although, yknow, with murder) about the relationship between two sisters
