Dynasty of Evil — Drew Karpyshyn

If the dark side's most powerful Master can capture the ultimate secret, the Sith will never die -- and neither will Darth Bane.

Twenty years have passed since Darth Bane, reigning Dark Lord of the Sith, reinvented the ancient order devoted to the dark side 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 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.

Zannah knows that her ruthless Master has begun to doubt her, and so she prepares for his downfall, plotting at last to wrest from Bane the mantle of Dark Lord of the Sith. Zannah pursues her Master from the grim depths of a ravaged world to the barren reaches of a desert outpost, where the future of the dark side's most powerful disciples will be decided by the final, fatal stroke of a lightsaber.
