To Every Purpose, A Season (фемслэш)

Two and a half years after the death of Ozai on the Day of Black Sun, life has settled down considerably for Royal wives Azula and Yue. Though she still struggles with her mental health, Azula is in a much better place - so good of a place that Zuko allows her to join Yue on her trip to the Northern Water Tribe.
Change is afoot in the North Pole, and Yue has been called home to help settle the battered Tribe regain its footing. But she faces challenges - namely, helping to reform the deeply sexist Tribe in ways that truly matter.
