Nightshade

Jillian Conrad always believed vampires weren’t real. But when she’s attacked by a desperate scientist, and injected with a serum meant to be a deadly poison against the undead, she realizes it’s all true. And when the scientist is shot dead in front of her, his secrets die with him. Declan Reyes hates vampires with all his heart—despite being half-vampire himself—and he knows the poison in Jillian’s veins could finally destroy the vampire king and his subjects. The serum makes her blood irresistible to all vampires—including Declan. One taste means death.
