Now this is new from wikipeidia, so take it for what you think it is, but I trust they have it right right now. I looked into news about when Legend of Korra is comeing back, and I found out something exciting. What I orginally thought was going to be two books to make two seasons is in reality two 26 episode seasons divided into two books a season. That means Legend of Korra is going to have four books and about 52 total episodes. Book two is coming out in 2013, and is called Spirit. That's all I got so far. I know that the books are all seperate stories and basically self-contained, only really haveing the character the same as a longer narative of their lives composing the whole series, or so I theorize.
This is where I got that [link]
and I hope you find it interesting. I'm looking forward to it all!
Is it Book Two yet?
