Audiobook Title:
The Chronicles of Pern: First Fall (Unabridged)
By: Anne McCaffrey

Building a new life on a distant world, braving the dreaded Thread that falls like silver rain from the sky only to destroy every living thing it touches, flying heroically on the wondrous dragons - The Dragonriders of Pern!

Anne McCaffrey suggests The Chronicles of Pern should be followed by The Dolphins of Pern.
