Book of Colors

Thai and his twin brother Avan are thrown into a world they never would have believed in. One where fairies and vampires and warewolves exist amongst humans and a species called the Angels keeps order between all. But while Thai and Avan are trying to adjust to their new lives, themselves, and keep a good distance from the Hunters intent on killing them, there's a war brewing and there is no telling who will live and who will die.
