The Avatar Twins-Book One

The avatar is the only bender who can control all four elements. But what if they where twins?
SACARA
She is thought to be the next avatar. She is not the most popular person at school, always seems to be getting into trouble, and always puts up a fight. That's right Sacara isn't the average ten year old girl.
TACRA
The twin of Sacara, you might think he's just like his sister.....think again. He is the strait A student, always does what he is told.... He is basically is that good boy that annoys the hell out of his sister and others. But he is the best earth bender in the family. And always keeps his family safe.....at least trys to.
EMBER
She is the new student, who is facenated by the avatar. She may or may not be a rich kid. She may or may not be destined to be the avatars fire bender teacher. That's something for you to find out.

New charicters will come in and pop out of this story, and if your curious to see if the next avatar were twins, then this is the story for you.
