I'm new to Tom Rob Smith, but bought the book after reading a very interesting article in the Times with Rob - where he spoke about the psychotic episode experienced by his own mother which inspired the book. Set mostly in the wilds of Sweden, it is a dark story brimming with atmosphere. We are never sure if the main character is telling the truth or not - or whether she is deluded about the string of sinister events which she experiences when moving to a remote farm. I found the ending entirely surprising, but totally logical in retrospect. The other aspect of this book which I loved was the style. The writing tells the story without resorting to tricks, or drawing attention to itself - but still delivered a novel full of menace and suspense. Now off to check out Tom's back catalogue.
