A previously unrelated incident from The Gardella Vampire Chronicles

In every generation, a Gardella is called to accept the family legacy of vampire slaying, and this time, Victoria Gardella Grantworth is chosen, on the eve of her debut, to carry the stake. But as she moves between the crush of ballrooms and dangerous, moonlit streets, Victoria's heart is torn between London's most eligible bachelor, the Marquess of Rockley, and her enigmatic ally, Sebastian Vioget. And when she comes face to face with the most powerful vampire in history, Victoria must ultimately make the choice between duty and love

In Italy, a powerful vampire is amassing the power to control the souls of the dead. Lady Victoria Gardella de Lacy-a vampire slayer for just over a year-races across Europe to stop what could be the most deadly army the Gardellas have ever faced. She is accompanied by Sebastian Vioget, a man as tempting as he is untrustworthy. But when Victoria discovers that she has been betrayed by one of her most trusted allies, the truth will challenge all her powers as a Venator-and as a woman

To gain access to the secrets of a legendary alchemist, Rome's vampires have allied themselves with creatures as evil and bloodthirsty as they are. The new leader of the city's vampire hunters-Lady Victoria Gardella Grantworth de Lacy-reluctantly turns to the enigmatic Sebastian Vioget for help, just as Maximilian Pesaro arrives to aid his fellow slayers, no matter what the sacrifice. Desire puts her at the mercy of Sebastian, while loyalty binds her to Max, but she does not know if she can trust either. Especially when a seductive vampire begins luring her into the shadows

After narrowly escaping Rome with her mortality, vampire hunter Lady Victoria Gardella Grantworth de Lacey returns to London—where not even sunrise can stop a vampire’s carnage. Not only is Victoria unable to detect the vampire with her heightened senses, but she’s being framed as the prime suspect behind the killings. Meanwhile, the legacy of a vampire’s touch has left his blood boiling in her veins and forces her to fight evil on two fronts—against the new breed of undead threatening London and the darkness within herself…

Demons, enemies of both mortals and the undead, have found their way to Earth. To defeat them, Victoria Gardella proposes an alliance between her slayers and Lilith’s vampires. But the vampire queen wants the former slayer Max Pesaro in return for her cooperation—a small price for the world, but a price Victoria is unwilling to pay
