Now broken and bruised, she begins a journey of self-discovery and survival in a new world where the strong prey upon the weak. When an aggressive military force rises up led by the power hungry Kuvira, the fate of the Earth Kingdom hangs in the balance and only the Avatar can set things right.The Legend of Korra, Book 4: Balance premieres on Friday, Oct. 3, on Nick.com and the Nick App. In addition, Books One, Two and Three are currently available for fans, so they can get all caught up before the premiere of Book Four at Nick.com
