Final destination

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 airbender named Brandon Ahlstrom. And although his airbending skills are great, he still has a lot to learn before he's ready to save anyone. But I believe Brandon can save the world.
