Publisher's Summary
''While Jedi Masters Saesee Tiin and Plo Koon fight to prevent a fleet of ships from falling into Separatist hands, Obi-Wan Kenobi discovers that the Separatists are not without dissension in their own ranks! On board the drifting hulk of a massive research ship, Obi-Wan finds himself taking sides with dark Jedi Quinlan Vos, who is wanted for the murder of a Senator, against another foe. Vos was once his friend, and the other enemy is one with whom Obi-Wan has crossed swords before. But has Obi-Wan been too hasty in deciding the lesser of two evils? Has Quin become the heartless killer everyone believes him to be? And will he help Obi-Wan escape the apparent death trap into which they fall, or abandon him to save his own skin?''
