I love Mary Stewart's books. The Moon-Spinners is one of my top 3 favorites! This book is ten times better than the movie (which totally changed the story)! A 20-something woman vacations in Greece and accidentally gets involved with a man who has a mysterious injury and a great desire not to be found. She knows something is up but he and his Greek friend refuse her help. She leaves them--only to run smack into the trouble they were hoping to allow her to avoid!
