The strange case of the sad sisters

This picture postcard place is on the edge of the area known as the Blue Mountains, so called because of the strange blue haze from the eucalyptus trees. But stranger still is the ancient Dreamtime story of the Three Sisters encased in the rock by their father's spell to save them from abduction by evil spirits. They have been waiting for millennia but will their father ever return? Or is he also entombed in stone, powerless to speak the words to set them free. A parent's nightmare.
