But when ever she thinks someone has wronged her--she won't stop til she makes it right again. Malice took Kori the day they were born. He told her that she had a twin brother, and that he was the one who killed their parents. Malice raised her to believe that Shock hated her and their parents. Kori remained hidden deep inside a secrete part of Malice's base--waiting for the day she meets her twin brother. Will Kori ever learn the truth behind their parents death?
