Sacrifice - Bolton, Sharon

Moving to remote Shetland has been unsettling enough for consultant surgeon Tora Hamilton; even before the gruesome discovery she makes one rain-drenched afternoon... Deep in the peat soil of her field she is shocked to find the perfectly preserved body of a young woman, a gaping hole where her heart has been brutally removed and three rune marks etched into her skin. The marks bear an eerie resemblance to carvings Tora has seen all over the islands, and she quickly uncovers disturbing links to an ancient legend. But as Tora investigates she is warned by the local police, her boss, and even her husband, to leave well alone. And even though it chills her to the bone to admit it... something tells her their concern isn't genuine.
