Query: One of the best vampire books I read.

I still have my original copy of this book bought in the 80's, When I first read it I couldn't put it down, vampires in mass taking over a major US city was just amazing, most vampire novels they are small towns or villages, this was a new take on what a plague of vampires can do, the book was scary, and portrayed vampires as the monsters they are, shame it is out of print, I have read the book at least a dozen times since I first bought it, I highly recommend this book if you love a vampire book like Salem's Lot, you won't be disappointed.
