Vampire, Not Monster - Angel's Guardian, #0

From the heights of NYC tenements, the vampire Maxim hunts for prey below. His prey of choice: murderers, rapists, drug dealers, the child molesters, the worst of the worst. On a sultry summer night, he witnesses a senseless murder, and the chase is on for a cold, merciless killer. But as the hunt intensifies, Maxim finds so much more than he expected.
