Avatar Korra, a headstrong, rebellious, feisty young woman who continually challenges and breaks with tradition, is on her quest to become a fully realized Avatar. In this story, the Avatar struggles to find balance within herself.
Book Four is set three years after Book Three. Now broken and bruised, Korra begins a journey of self-discovery and survival as 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.
