Book X (chronological) of Darkover. When the Terran Empire first colonised Darkover, they were grateful to find some human life, mixed as it was with strange alien creatures.  Yet to the highly sophisticated technocrats from Earth, the ancient Darkovan civilisation presents an impenetrable barrier of medieval warring clans – many of them possessing highly developed psychic powers.  Strangest of all is a band of women known as the Free Amazons – a law unto themselves.  They hold the key to the mystery of the planet.
