Star Wars: Darth Bane: Rule of Two

As the last surviving Sith, Darth Bane promulgated a harsh new directive: the Rule of Two. Now he is ready to put his policy into action, and he thinks he has found the key element that will make his triumph complete: a student to train in the ways of the dark side. But there is one who is determined to stop Darth Bane: Johun Othone, Padawan to Jedi Master Lord Hoth, who died at Bane's hands in the last great Sith War.--From publisher description.
