Vampires Vs. Aliens — Keith B. Darrell

They came from a dying world to steal the Earth's water but they didn't anticipate resistance from the vampires, who realize the aliens' plans would doom the human race... depriving the planet's furtive vampire population of its sole food source.. Now the vampires must wage a secret war against the invaders while hiding their own existence from the humans. With the unanticipated destruction of their homeworld, the aliens have become refugees -- but will the Earth perceive them as victims or villains? Reporter Pete Riley discovers the existence of both the aliens and the vampires but that knowledge may cost him his life. As the aliens choose a new leader, forcing Kevian and Kira to assume new roles, two new aliens arrive, precipitating a conflict between church and state. New arrivals also move into the mansion, including a familiar New Blood, an Ancient vampire older than the Earth itself, and an Elder hiding a deadly secret, each bringing new challenges to Gaunt and his family of vampires.
