I Am Avatar Korra

In the midst of Avatar Korra's defeat of Vaatu, the world decides that it doesn't need its Avatar any more. Korra is chased out of Republic City and forced out into a dangerous and hostile world that would do anything to get rid of her. Alienated from her friends, family and allies, Korra takes on different identities as she travels the world, looking for an answer to a very simple question.
Where did I go wrong?
When confronted with an old friend and ties to her old life returning, what will happen when the world decides its Avatar has been in hiding for too long?
