Blood Roses by Lindsay J. Pryor

“She was supposed to kill vampires, not save them. Those were the rules. That was the lore.” A rare and powerful witch whose blood is lethal to vampires, Leila has always viewed her serryn abilities as a curse. After seeing her mother slaughtered as a child, Leila longs for a safe, quiet life. That wish is shattered by Caleb Dehain – a vampire with a dark past and a darker heart. The most feared serryn hunter of his generation, Caleb now needs the help of one of the witches he despises to save his dying brother. A serryn who has no reason to help him. Except that he has her sister. Caleb and Leila are each other’s worst nightmare – but the slow-burning spark of attraction between them is undeniable. Will Leila’s blood be his damnation? Or could her kiss be his salvation?
