Midnight

Jo Harding never thought of herself as a villain. At seventeen, her only adversary was her chronic illness. Yet, when a group of superheroes separates Jo from her brother, nothing will stop her from getting Jamie back.
After waking up in a morgue, Jo finds herself with no money, nowhere to go, and no way of letting her famous twin brother know she is still alive. To make matters even worse, she starts exhibiting uncontrollable powers. Afraid and in a body she can't rely upon, Jo scours the town with help from a bookstore owner and his former-military husband. Each encounter leads the superheroes to believe they are fighting a villain. However, the real villain is the leader they are following, the doctor that left Jo to die.
