Plot synopsis: Sacrifice is the story of consultant surgeon, Tora Hamilton, who moves with her husband, Duncan, to the remote Shetland Islands, 100 miles off the north-east coast of Scotland. Deep in the peat soil around her new home, Tora discovers the body of a young woman with rune marks carved into her skin and a gaping hole where her heart once beat. Ignoring warnings to leave well alone, Tora uncovers terrifying links to a legend that might never have been confined to the pages of the story-books.
