Which name for the main girl in my story?

It has to be a nickname aswell so it's easier to type in, Aviana (Av) Alegra (Alley) or Scarlet (Scar) any other sugestions are apreciated, If u'd like to help me there's a link to my story, rough draft that my neice did on sims 2 adding my story line. Since the site is down I'll give u a descrption, She's a reckless, adreine seeking, independant girl. Plz help, thx
