Avatar: the last airbender#the search part 3

Avatar Aang travels to the spirit world to parley with an ancient power; bringing Fire Lord Zuko ever closer to discovering the truth about his mother's fate—and his own past.

Yet Zuko's sister Azula is becoming increasingly dangerous; threatening to ruin everything that Zuko; Aang; Katara; and Sokka have struggled to achieve on their search!
