Darth Bane: Dynasty of Evil (Star Wars: Darth Bane, #3)

Twenty years have passed since Darth Bane, reigning Dark Lord of the Sith, demolished the ancient order devoted to the dark side and reinvented it as a circle of two: one Master to wield the power and pass on the wisdom and one apprentice to learn, challenge and ultimately usurp the Dark Lord in a duel to the death. But Bane's acolyte, Zannah, has yet to engage her Master in mortal combat and prove herself a worthy successor. Determined that the sith dream of galactic domination will not die with him, Bane vows to learn the secret of a forgotten Dark Lord that will assure the Sith's immortality--and his own.
