The Time of Feasting
By Mick Farren, 1996
Series: Nosferatu Chronicles

"A colony of vampires lives unrevealed in New York City. But with The Time of Feasting at hand they must make the warm kill and drink the living blood. The colony is vulnerable now both from the younger vampires, tired of living in hiding and from a drunken ex-priest and a tenacious city cop who have begun to suspect what they really are."
