After eighty-six years of war, a new Avatar is born into the Southern Water Tribe. Fourteen year later, Katara realizes the full extent of her powers when she finds a child with strangely familiar abilities frozen in an iceberg and a prince comes searching for her. Along with Sokka and Aang, she flees for the North Pole, and Zuko is never far behind. *Eventual Zutara romance*

When another impossible mission takes Zuko away from home, Azula sends him off with a single promise: to keep Ozai from learning the truth about what happened in Ba Sing Se. While he tries to survive a hostile corner of the Fire Nation, Katara is left to fend for herself as her friends complete their training. As their paths intertwine, Azula's promise returns to haunt them both.
