New look,old life.

Petra gets badly hurt during a battle with Eily and gets sweet new robot arms,legs, and waist. They make her look normal when after she's not. When Branden and Eily return for more they kidnap Petra's little sister, Lilliana (or lilly for short). Can Petra and her two brothers, AJ and Lukas save Lilly and stop Eily and Branden before it's too late?
