Det här kan vara Sharon Webbs " Ram Song ", den tredje i hennes " Earth Child " -trilogi; Det var ursprungligen publicerat 1985. Det enda jag kan komma ihåg om boken är kristallkruvorna.
On the planet Aulos, a strange beam that disorients people is interrupting a yearly festival; the immortal Kurt Kraus and the starship Ram are called to meet the emergency. Sequel to Earthchild and Earth song.
