I really enjoyed this book.
Set in Norway, this crime thriller is probably trying to cash in on the Dragon Tattoo trilogy, but the carefully built storyline is a pleasure to read. The heroine is not very likeable as a person (and I suspect deliberately tries to annoy the reader) - this makes it more interesting to read; and the observation of the different people involved was marvellous. And yes, it does, of course, have a twist.
I read this all in one sitting; though it was a long plane ride! A great read if you like a good whodunnit, with a difference.
Worthwhile, also, mentioning that the Kindle version is perfectly delivered and formatted.
