An inferno amongst the glaciers

Another installment of my "Azula saga." Apparently, Aang's life is in danger again. Turns out burning Katara's hands wasn't such a good idea after all, and Azula intends to avenge her. Implied future Azutara. Takes place before the rest of my Azula fics, except for "Trust, stupidity, what's the difference?" and "The devil within" Takes place two years after those stories.
