Shadows and Embers Book 1: The Mission

Zuko has two sisters. Twin prodigies, who have never failed Ozai. This book explores how the story would have changed if the Firelord had two daughters and sent them both after Zuko instead of just Azula. It will diverge from canon a lot eventually.

Rated:16 (Violence and Darker themes) (no lemon because they are kids,at most it'll be implyed like zuko and Mai and sokka and suki)

Narrated in third person omniscient point of view.
