Agni and La (фемслэш)

Six years after the war, Fire Lord Azula rules through calculated peace rather than conquest. When she arrives in the Southern Water Tribe to negotiate reparations, Katara expects manipulation, not to become part of the terms herself. With everyone against them one way or another, it is them against the world.
Political Azutara. Slow burn. More tags will be added. Will become explicit in future.
Aka that one Tumblr prompt which is now turning to a full-fledged fanfic. Where Azula and Katara bickered a lot, decided the other one is not so bad, found a long-lost mother, found dragons, rebuild two nations and finally fell in love.
