Book II of Crystal Singer. She was one of the Crystal singers, the elite, mysterious ones who cut the crystals from the planet Ballybran - precious, glittering crystals without which the Universe could not function. Sent to the planet Optheria to repair the famous crystal organ, she was - at first - accorded all the honour and pomp due to her rank. Then her life was threatened. She was wounded, then kidnapped, isolated at the very heart of the planet, knowing that she alone had the power to confront and destroy the evil that had permeated the world of Optheria.
