As Shadows Fade (The Gardella Vampire Chronicles #5)

Directly descended from the very first vampire hunter in the Gardella family, Victoria knows she must continue the lineage so humanity will have protectors against the undead. While Sebastian Vioget appears to be both the perfect warrior and lover to ensure the Gardella Legacy, Victoria cannot forget Max Pesaro - the former slayer still haunted by the vampire queen Lilith's obsession with him. But it is Lilith's obsession that may save all of humanity. Demons, enemies of both mortals and the undead, have found their way to earth. To defeat them, vampires and slayers must fight side by side. But Lilith wants Max in return for her cooperation; a small price for the world, but too high a price for Victoria.
