Vampires Vs. Aliens, Book Seven — Keith B. Darrell

They came from another dimension -- a microscopic interdimensional void -- seeking bodies to inhabit so they might exist in our dimension. And what better host for these alien invaders than Earth's apex predators: vampires! Both humanity and vampires are at risk, and neither is aware the alien Void Wraiths already walk among them and are infiltrating their abodes.                                              In Book 7, New Beginnings, Alexander plots to unleash the body-snatching Void Wraiths on the vampires at the mansion, and the Conclave of Elders wants to put Gaunt and Sebastian on trial. High-schooler Benton Cartwright arrives with a deadly secret and an uncanny ability that might save the world.
