Azula Apart (фемслэш)

Personal is political, especially for Princess Azula.
Set following Azula's escape from the asylum and her journey across the Fire Nation, Azula arrives alone and friendless in the Earth Kingdom, looking to carve out a purpose for a former child general in a post-war world.

It can be read independent of All That Remains Is Smoke but I would recommend reading the whole series as part of Azula's ongoing redemption.
