Unraveled

Since coming to Crossroads, Oklahoma, former outcast Aden Stone has been living the good life. Never mind that one of his best friends is a werewolf, his girlfriend is a vampire princess who hungers for his blood, and he's supposed to be crowned Vampire King - while still a human! Well, kind of.
With four - oops, three now - human souls living inside his head, Aden has always been "different" himself. These souls can time-travel, raise the dead, possess another's mind and, his least favorite these days, tell the future.
