The Fire Lord's Concubine
Fire Lord Zuko rules from a throne still warm from the war that won it to him.The sages need an heir, so they comb every province of the Fire Nation until they find you: a weaver's daughter from a coastal village the war bled dry twice, and the loveliest girl they have ever put forward for his bed. He swore he would never hoard women the way his father did. You were raised to despise the boy-king who wears his father's crown. Neither of you is going to keep your promise.
