This troper is always wary of stories in which Aang is dead and another character - usually a major one - is the new Avatar. Especially Zuko. Fortunately this story, while still in its early stages, is shown to be competantly written and carefully plotted out. The writer works hard to make Zuko's feelings about the matter realistic, and everyone else is given believable reactions - In-Character for canon characters, and plausible for O Cs
. Further, it avoids the old, dead cliche of using Sokka and Katara as the Avatar's companions dead early in the plot, and looks set for some really creative writing in the future. Definitely commendable.
