From the introduction: Vampires exist. Vampires stalk our cities, finding nourishment in the crimson lifeblood of an unwitting and helpless society. They are among us. They have been with us for centuries. The signs have been there all along, and yet mankind has not heeded them. People allow themselves to suspend disbelief long enough to be scared by a motion picture or a well told ghost story, but there is always the sunlight to welcome them back into their ignorant waking slumber.
