The renegades of Pern

Blurb

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. The exploration of the Southern Continent and discovery of ancient human relics there also figure in the novel, which ends where All the Weyrs of Pern begins.
