Bleeding Hearts by Alyxandra Harvey
Lucy's cousin Christabel has come to live in Violet Hill, and adjusting to the difference between life in a small mountain town and her home in the city is difficult. The strict curfew that Lucy's parents enforce is hard to respect. Surely something really dangerous couldn't possibly happen in this tiny town. But Christabel starts to notice some mysterious happenings, and it seems like Lucy, her boyfriend Nicholas and his brother Connor are all in on a secret that Christabel doesn't understand - one that seems deadly serious. Although she won't admit it, Christabel would love to be in on any secret with Connor Drake. When Christabel is kidnapped by the ruthless Hel-Blar vampires, Lucy and Connor finally fill her in on all the undead drama. Together, they must find a way to stamp out the Hel-Blar for good.
