Yes, four books 52 episodes book 2 is Spirits
At the moment, no. There were a total of four books in the Eragon series.
Book 4??? There's no book four, sorry. But anyways, if Ozai did, then Avatar would keep going and going and going, right? And I think the creators decided to leave it like that. It was good that they did that though. IMHO. ---- http://en.wikipedia.org/wiki/Avatar_The_Last_Airbender
There will never, as far as we know right now, be a Book Four. They are creating an Avatar Live-Action Movie, but the television series is ended, seeing as all of the Aang's main conflicts are concluded in the Sozin's Comet episodes.
