Blood Blade (Skinners, Book 1)

There is a world you don't know about, inhabited by supernatural creatures of darkness - vampires, werewolves, and all manner of savage, impossible beasts that live for terror and slaughter and blood. They are all around us but you cannot see them, for knowledge of their presence - so close and so hungry - would surely drive any ordinary human insane. But for centuries a special breed of hunter has kept the monsters at bay, preventing them from breaking through the increasingly fragile barriers protecting our mortal realm. These guardians are called skinners. But beware . . . for there are very few of them left.
