Katara is determined to save the world...or at least to never stop trying. With strength and maturity beyond her years, she's the glue that holds the group together. She's still learning to master her waterbending abilities, but her full time job of keeping Avatar Aang out of harm's way may be all the practice she needs.
With the Fire Nation on the brink of global domination, a young girl and her brother discover a 12-year old Airbender who reveals himself as the Avatar. Will this irresponsible kid accept his destiny in time to save the world?
