I really enjoyed this book. I was totally gripped and enthralled from the start. I like that the story was told from Alex's point of view and that Olivia was narrator for some of it too. I was totally surprised by the ending. The Setting of the Orknies added to the atmosphere. It also made it a really good thriller as it meant that the culprit had to be someone that everyone knew. The friendship between Alex and Detective Inspector Birken is very well written and the other characters are well described which added to my empathy with the characters.
