Four years have passed since the end of the war, but as they meet again and encounter many obstacles, Zuko and Katara realize that whom their hearts truly burn for is one another. Can they love each other knowing they will hurt those that love them? What will become of them when a new enemy appears with a vengeful plot to destroy everything they had worked for to bring peace?

In Ba Sing Sae, Zuko meets Rayna, the newest member of team avatar. Rayna doesn't know who Zuko is or his past with team avatar, and Zuko doesn't know that Rayna is apart of team avatar. When they meet, they begin to fall for each other, unaware of the problems to come.

Book 4 Air: A new chapter begins where questions will be answered and friendships will be tested. An epic unknown twist draws near for the young avatar and everyone he has come to know and love. Zutara, Sukka, and Taang pairings. Rated "M" in later chaps.
