Avatar the Last Airbender: Forbidden Love

Water... Earth... Fire... Air. Long ago, the four nations lived together in harmony. Then everything changed when the Fire Nation attacked. Only the Avatar, master of all four elements, could stop them. But when the world needed him most, he vanished. A hundred years passed and my brother and I discovered the new Avatar, an Air bender named Aang. And although his Air bending skills are great, he still has a lot to learn before he's ready to save anyone. But I believe Aang can save the world...
One hundred years have passed since the Avatar was last seen. However, news of his awakening spreads across the world like wildfire. Unbeknownst to the rest of the world, in a small town that was hidden on an island that was out in the middle of nowhere, a young girl was learning to Bend all of the Elements. Though she was not the next Avatar since the present one had just awoken again, she becomes quite proficient in bending the four Elements to her will. As she grows older, news of her abilities travels around the word, and word reaches both the Avatar and his friend and Prince Zuko, a young Fire Bender who is determined to capture the Avatar and present him to his Father, Fire Lord Ozai, in hopes of regaining the honour he lost. In hopes that somehow going for the girl to capture her and use her as bait for the Avatar, Zuko makes for the island as well. Little does he know what is waiting him on the island. In the desperate fight to obtain the girl, she is poisoned and both he and the Avatar must work together in order to retrieve the flower that acts as an antidote to the poison. Can he do it? Will he be able to work alongside the Avatar who he has been desperately trying to capture for a while now? Or will he use the advantage given to him to take the Avatar prisoner?
