The Light at the End is a 1986 vampire novel by John Skipp & Craig Spector which became a New York Times bestseller and is often credited as the book that started the splatterpunk movement.
[1][2][3] The book takes place in the 1980s punk subculture of New York City.
While riding the subway, a young street punk named Rudy Pasko is attacked and turned by an old vampire.
Drunk off his new power, Rudy takes to the nightlife and goes on a murder spree, but his actions lead to the formation of a posse composed of several local messengers, artists, and working class citizens who devise a plan to hunt him through the New York underground.
Coincidentally, in the Season Five episode, "Fool For Love" there is a scene in which Spike fights a hunter in the subways of New York.
