Rises The Night (The Gardella Vampire Chronicles 2)

"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."
