Moreta

Anne McCaffrey draws the reader back in time to an earlier Pern to tell the story of one of Pern's great and true heroines. An air of pleasant anticipation hung so thickly over the Halls, Holds and Weyrs of Pern that it had affected even the businesslike ways of Moreta, the Weyrwoman of Fort Weyr, where her dragon, Queen Orlith, would soon clutch.
