Goddess and Protector

A girl with powers almost god like? Woah. Isn't that strange. Not only that. There's others like her with powers like gods? For example, her twin. Shelby and Carmelita Bowers, twins, having powers of gods but each different. In this world these girls believe nothing of gods, well that is until they are approached by a demon like silver eyed freak, in which they're brutally attacked but manage to escape, with the help of their gifts. Shelby is the outgoing one of the twins and Carmelita (Carmel for short) is the exact opposite. While Shelby is like the night, a wonder. Carmel is like the day, an angel full of light. After they lose they home they only have one option. Going to find answers. Which includes discovering searches of the unknown facts about their parents, from whom they've never knew for the 17 years of their life. Which also includes them going to an Academy. To be more specific The Celestial Academy.
