ISBN13: 9781435109629 Originally published in two separate volumes: Blood Is Not Enough (1989) and A Whisper of Blood (1991) Not all vampires shun sunlight and not all drink blood. In A Whisper of Blood you will encounter thirty-five of the most horrifying vampires you are ever likely to meet: monsters who often walk by day, look and think very much like you, and differ from ordinary people primarily by the zeal with which they prey upon others. You won't know them when you see them - and you may not even recognize their appetite for our destruction.
