Avatar The Last Airbender: Story of Ami

Ami was born in Omashu to two powerful Earthbenders, who have a tremendous reputation of being the bravest warriors of the entire Earth Kingdom. However, she was born a nonbender while her older brother Kenta was born a very gifted and talented Earthbender.
One day, when Ami was just 2 years old, her parents vanished and never came back, leaving her to be raised by her older brother. But then, he disappears too when she turns 7. Ami wonders if her family has been captured by the ever so fierce Fire Nation under Ozai's orders or if they left her due to her being a nonbender.
She fends for herself for about a year until she is taken in under the wing of the crazy king Bumi, making her the Princess of Omashu. Her life seems under control until Aang, Katara, and Sokka show up to Omashu. And King Bumi decides that Ami should help guide the Young Avatar around the world.
Will Ami succeed in finding her parents while she's with the Avatar?
Or will she too vanish away from humanity?
