By Gene Luen Yang
A graphic novel that picks up right after the show's finale, following Aang, Zuko, Katara, and Sokka into the messy work of rebuilding a world the Hundred Year War broke.
The war is over. Zuko rules the Fire Nation now, and the ugly cleanup begins: colonies the Fire Nation planted inside the Earth Kingdom generations ago are supposed to be dismantled, and the families who have lived there their whole lives refuse to pack up and leave. Aang and his friends sign on with the Harmony Restoration Movement to make it happen peacefully, but the peace keeps buckling. And in one dark scene, Zuko makes Aang swear that if he ever turns cruel like his father, Aang will end him for good. Gurihiru draws it all in the bright, exact style of the series, and Gene Luen Yang wrote it as the official next chapter of the story.
This one is really for a child who already loves the show. If your child watched all three seasons and was crushed when it ended, here is the answer that it keeps going. It is the official continuation, blessed by the creators and drawn to look exactly like the series, so a reluctant reader gets to stay in a world they already know while the art does most of the lifting. The team is here, the humor is here, the bending fights are here. What is new is watching how much work peace actually takes. It is Part 1 of a trilogy with more collected volumes after it, so a hooked child has a good long stretch ahead.
