After Dark - The After Dark Series Book One

Author Dean Alan Conrad- Back cover description is as follows: The homeless disappear.  It happens every day in a large city. Have they moved away? Gone to rehab? Died of overdoses and carted away, nameless, to the city morgue? No one seems to care, except a small band of people who live in tents and boxes on the sidewalks. They know their friends have been taken by the Whistlers, animals that hunt in the park to feed their vampire masters. The homeless in the know have escaped from the Whistlers and the vampires, who live in the basement of After Dark, a historic restaurant near the city's new baseball stadium, a hub of city life.
