Wow, I am so impressed! 
 I arrived late to the whole "who is Robert Galbraith" enigma; so I already knew this was written by J.K. and feared it would have the same fantastical tone as HP. It's so hard for best selling authors to branch out into other genres, they get type cast and most are doomed to fail. Same thing that happens with actors (think the cast of Friends, minus Jennifer Aniston). So I was pleasantly surprised to find the tone so different from HP and very.. adult! 
 J.K. aside, I really enjoyed this book. I loved the characters, their relationship dynamic and the way the mystery played out. I've taken one star off though as I wasn't convinced with the killers motives or how it all played out in the end. 
 This was a light and fun book to read, looking forward to the rest of the series and for more Cormoran and Robin.
