I just finished reading both chapters and I am already hooked by this story Please update soon, this is an amazing story and I love where this is going. If you ever get this published,please let me know. I would live to buy a story like this.

Interesting premise and generally a good start, but I would STRONGLY suggest finding a new title. There's already two major films (one with a series) that came out not too long ago with the title Avatar. While I don't think it's a trademark violation since it's a single word, it isn't very distinctive.

You may be able to leave the word Avatar in the title if it's really important to the story, but I'd find someway to make it distinctive...

Kind of like the full title of one Avatar is "Avatar: The Last Airbender". The addition of those three words makes it's trademarkable. Just something to think about.
