The Guardians of the Night

Vampires. They hunt in every major city, hidden by the crowds, shielded by disbelief. They are Killers, and their prey is human. But not all vampires are Killers. The Guardians of the Night protect humans--sacrificing the superior physical and psychic strength they would gain by feeding on humans. But, in this paranormal romance series by Jenna Black, the Guardians walk a thin line, for even a single kill could leave them helplessly addicted to murder.
