Aya

Aya is Katara and Sokka's little sister(so original) and happens to be just like her brother; she isn't a bender. Physically, she loves that her sister is a bender, but mentally she envies her sister and is sad she isn't one. Aya believes she has bending abilities but just hasn't discovered them yet. She has hope that maybe going on an adventure to save the world with her siblings and the avatar could strike her potential bending skills.

Book 2 and Book 3 are out now!
