The Moon-Spinners — Mary Stewart

Young, beautiful, and adventurous Nicola Ferris loves her life as a secretary at the British Embassy on Greece. On leave from her job as a secretary in Athens, has been looking forward to a quiet week's holiday in the lush island of Crete, enjoying the wild flowers and the company of her cousin Frances. Then on her day off, her impulse led her on a little-used path into the foreboding White Mountains. She links up with two hiking companions who have inadvertently stumbled upon a scene of blood vengeance, that involving a young Englishman and a group of people tied together by blood and the bonds of greed.

For the first time in her life Nicola meets a man and a situation she cannot deal with... A man in hiding -- for reasons he could not explain. Warned to stay away, Nicola was unable to obey. And before she realized what she had uncovered, she found herself thrust into the midst of an alarming plot in which she would become the prey... And suddenly the life Nicola adores is in danger of coming to an abrupt, brutal, and terrifying end....
