Alpha: The Hierarchy, Book 1 by I. Ogunbase

Vampires exist and have finally been categorised into three main groups by the remaining governments dealing with the outbreak; The Ferals, blind and grey skinned, the Stalkers, pack hunters and the Mirrors, dark reflections of humanity. When a researcher goes missing, Matt is thrust out into the world to find them and bring them back into the safety of the Walled Cities. Except, rumours of a new category is spreading. And at the rate at which events are going, it might be already too late for survival.
