There is increasing tension between Obi-Wan Kenobi and Anakin Skywalker. Anakin still feels responsible for the death of a Jedi Council member — a guilt he does not think Obi-Wan can help him overcome.
Obi-Wan feels he is a less-than-perfect Master — trying to teach a less-than-perfect apprentice.
It is with these feelings that Obi-Wan and Anakin head to the last free planets of the Uziel system to make a daring rescue attempt. When the rescue goes awry and Anakin is taken prisoner, the Master and Padawan must overcome their conflict — or a planet will die.
