Justine was born and raised in England. When she was seven years old, she saw her best friend Cheryl killed when she was struck by a car while attempting to cross a busy street. The anger and loneliness she felt over her friend's death strongly influenced her. By the time she was seventeen, she had adopted a belief system which blended ecological activism with magic. She joined the environmentalist movement and began destroying cars with sledgehammers and petrol bombs.
