The Renegades of Pern - Dragonriders of Pern Book 10
Description from the back of the book
They were the misfits, the outcasts, the murderers without Hold or Crafthall. Some were resentful, some sought vengeance, but it was not until Thella, Lady Holder of Telgar, began to weld them together into a terrifying and brilliantly evil clan that they became the Renegades of Pern.
