Every two hundred years or so shimmering Threads fall from space raining death & black ruin on Pern. The great dragons of Pern hurl themselves through the beleagured skies flaming tongues of fire to destroy deadly Thread & save the Planet. But it was not Threadfall that made young Menolly unhappy. It was her father who betrayed her ambition to be a Harper who thwarted her love of music. Menolly had no choice but to run away. When suddenly she came upon a group of fire lizards wild & smaller relatives of the fire-breathing dragons she let her music swirl around them. She taught nine of them to sing. Suddenly Menolly was no longer alone -- she was Mistress of Music & Ward of the dazzling fire dragons.
