The Hundred Year War is over. Peace has been declared. Aang is hailed as the world's savior, and Zuko, newly crowned Fire Lord, struggles to hold together a nation built on scars. Katara travels between nations as both ambassador and healer. Though she and Aang are close-everyone assumes they'll end up together-something unspoken lingers between her and Zuko. Something heavy. Something dangerous. In this world, peace is public, but personal wars still rage.
