The Renegades of Pern
The Renegades of Pern is a science fiction novel by the American-Irish author Anne McCaffrey. It was the tenth book published in the "Dragonriders of Pern" series by Anne or her son Todd McCaffrey. It was first published in 1989. Like "Nerilka's Story", "The Renegades of Pern" is a departure from the normal perspective for the "Dragonrider" books, presenting a parallel viewpoint, this time running concurrent with the original trilogy; the book begins at the time of "Dragonflight" and ends a little after the ending of "The White Dragon". It tells several stories, tied  together by the figure of Thella, renegade sister of Larad (Lord Holder of Telgar Hold). The exploration of the Southern Continent and discovery of ancient human relics there (including the activities of Piemur and Menolly from the Harper Hall trilogy) also figure in the novel, which ends where "All the Weyrs of Pern" begins.
