It is whispered that the Old Ones still haunt Mesa Verde-the restless spirits of the Anasazi, who carved their homes in the mountain's face eight centuries ago ... and then disappeared from the Earth. Newly assigned national parks ranger Anna Pigeon seeks solace from her own personal demons in the ancient cave dwellings of a vanished Native American civilization. But an inexplicable illness affecting visitors to the popular Colorado landmark has dragged her from her reverie - as have two mysterious tragedies: the death of a child ... and the murder of a friend. And now she must find the very human source of the evil wind that is blowing through the ruins. For it threatens more innocent lives, Mother Nature ... and Anna herself.
