The Last Airbender

Four nations, four elements, and one child frozen in an iceberg for a hundred years while the Fire Nation burned its way across the map. Aang is the Avatar — the only person who can bend all four elements and the only one obliged to — and he is twelve, and he ran away once already. The world is built out of borrowed Asian and Inuit traditions with unusual care: bending as martial art, spirits carrying their own grievances, and a war whose damage is counted in ordinary lives. The prose shelf runs alongside the animation. The Chronicles of the Avatar novels go back to Aang's predecessors — Kyoshi, the tallest and least forgiving Avatar the world has had, and Yangchen before her — and are written for readers who want politics, earth-kingdom crime and moral cost at novel length. Beside them sit the Legend of Korra tie-ins, the novelisations of Aang's own story, and the newer Avatar Legends material. The register is what made this world unusual in the first place: comedy and genocide in the same story, a villain redeemed slowly and at price, children carrying far more than they should. Start with The Rise of Kyoshi if you want a novel that stands entirely on its own and does not need the show; start with the Aang novelisations if you want the story you already know, in print.
