Ooh, interesting. Another one where I have no idea what to expect. (And I think the sequel is released in a couple of weeks).
I had this one on my Kindle before it was revealed that new author 'Robert Galbraith' was actually the moderately successful J K Rowling (I think you may have heard of her).
I am intrigued to read her 'adult' voice when I've only known her as a children's or YA author.
