Help, I can't remember the name of the story but it's a Katara and Zuko story. I remember most of what happens in the story.
Katara and Zuko are taken to an island to learn bending from the first benders, there are four benders, fire, water, earth and air, on this island and there dragons. The fire and water dragons teach Katara and Zuko. They live on the island for around 6 years and become masters and fall in love and get married to each other while on the island. Then after the 6 years they leave and start helping to end the war. Mean while Ozai is having Azula's arranged marriage to one of his peoples son's. Katara and Zuko going around taking back places to get attention and they take back the poles and break prisoners out of boiling rock and other stuff.
