they also released the next Darth Bane title, with a summary to go:
Darth Bane: Dynasty of Evil
The Sith are gone -- all except Darth Bane, creator of the "Rule of Two," which states that the new Sith Order will consist of only two: a Master and an apprentice. But how does one train an apprentice whose ultimate goal -- and proof of success -- must be to kill the Master?
Darth Bane is beginning to suffer the effects of drawing heavily on the dark side of the Force for so many years. At the same time, he's beginning to doubt his apprentice, Zannah, because she hasn't yet tried to kill him and take his power. Is she weak? Unworthy of being his apprentice? When he learns of an ancient Sith artifact that might hold the secret to immortal life, he heads out in search of it alone. But Zannah is anything but weak, and now that she has glimpsed his worries, she knows that the time is ripe to take him on. The Forces of evil will clash in spectacular battle, with the future of the Sith hanging in the balance!
