Dragon's Fire

On the planet Pern, the deadly Thread is falling again, and the supply of fire-stone needed for dragons to fight back is running dangerously low. Three young people—a miner's son, a holder's daughter, and a dragonrider—must find a way to secure the planet's future before the skies turn lethal. Their search for resources leads them into the deep, forgotten places of their world where the survival of their civilization is at stake.
