Traitor (Avatar the Last Airbender Fanfiction)

Ailene was supposed to help end the war. Not fall in love with the Fire Nation prince. Years ago, she was banished for a secret no one was supposed to find, leaving behind the boy who held her heart and the mission that nearly killed her. Now, she's back with Team Avatar, wielding violet fire and a broken past. But when Zuko offers her everything she once wanted-home, love, him-right before betraying the Avatar, Ailene is forced to decide what kind of fire she'll be: the kind that destroys, or the kind that saves.
She's not the girl he remembers.
And he's no longer the boy she loved.
