Finding herself

The Morelli family lost their principessa when she was only one year old. They tried their best to find her but it was always a dead end.
Aria Brooke Davis had a rough past of being abused from when she was seven but when her knight and shinning amour found her on the streets when she was only twelve takes her under his wing and trains her to the well known assasian.
What happens when her knight and shinning amour dies and she is forced to move back with her real six overprotective brothers and parents after 15 years?
Aria is a badass ,egotastic,sarcastic and full of secrets that would cause all hell to break loose if they were discovered.
