Dusa Thrasman is 16 years old and in trouble. Snakes haunt her dreams, leaving her afraid to sleep, exhausted and ill. Her doctor has tried everything. Then Dusa sees a TV interview with two doctors, the Gordon sisters. Their specialty: curing snake dreamers. But in order to be treated, she must go with the Gordons to their remote clinic on an isolated Greek island. When Dusa arrives in Greece, peculiar things happen.  At the clinic, the staff and the other patients have run off.

  Only Perse and his father, the Gordons' servants, are left. Perse tries to warn Dusa about the Gordons, but his broken English is hard to understand. When the Gordons hypnotize Dusa, what are they trying to find out?  And who was their sister, the original snake dreamer, the one they want to make whole again?.
