Moreta : Dragonlady of Pern

Some fourteen hundred turns after men first came to Pern rode Moreta, on her great golden dragon, Orlith. It was towards the end of the Pass of the Red Star -- a time when every living creature on Pern was threatened by Threadfall -- when the courage and daring of dragons and their riders was all that kept the planet from extinction. And then, at the height of the battle against Thread, came a new and terrible evil. Moreta, in one last superhuman endeavour, was to save her people, and become the greatest legend of dragonlore until the end of time.
