From the back of the book:
It is the story of Lewis Kindred, a soldier who returned from Vietnam a different man. Cursed by the loss of his legs but blessed with unearthly new powers - he is driven by a strange, unspeakable hunger. And he is not alone. A stranger in a world of mortals, he feels the presence of others like himself. Others who hunt. Others who kill. But there's one difference between Kindred and his kin. Kindred will not surrender his last shred of humanity.
