I don't know what this woman wants revenge for, I really don't remember but it must have been stupid if I don't recall. I really feel like her character was nothing more than she evil now. Some mortal can just sell her soul and be as powerful as an evil g**. People would be like take my soul please. Who is giving her that much power that they must vastly exceed an evil g** to have enough to spare to this woman just for her soul.
Read Cursed Princess Club, it's finished and fantastic.
