Corvus Revan and the Crown of Blades

Corvus Revan isn't your average American wizard. He is a target of one of the most evil Dark Wizards in American History: Malevick. He is heading straight for a deadly Wizarding War and he has no clue why. Why can he speak to snakes? Why are his eyes always turning red? Why is he being hunted anyways? And why in Merlin's name does he have both an older brother and a younger sister?
