Irishwoman Mary Reynold's journey from rank outsider to winner of a Gold Medal at the Chelsea Flower Show.

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.
