Snake Dreamer Hardcover – May 11, 1998 by Priscilla Galloway 
 
Dusa Thrasman is 16 years old and in trouble. Snakes are haunting her dreams, leaving her afraid to sleep, exhausted and ill. Her doctor has tried everything, but the medications only make things worse. Then Dusa sees a television interview with two doctors, the Gordon sisters. Their specialty: curing snake dreamers. Dusa is both frightened and relieved to hear them discuss her illness as if it's a real medical condition, something with a cure! But to be treated she must go with the Gordons to their remote clinic on an isolated Greek island.

From the moment Dusa arrives in Greece peculiar things happen. At the clinic, the staff and other patients have run off. The only people left are a boy named Perse and his father, the Gordons' servants. Perse tries to warn Dusa about the Gordons, but his broken English is hard to understand. Can he really mean that they haven't aged in a hundred years? What are they trying to find out when they hypnotize Dusa? And who was their sister, the original snake dreamer, the one they want to make whole again?
