Enemy — Lacy Yager

Enemy A young adult novel She's the unlikeliest vampire hunter ever. A scientist. Seventeen-year-old science prodigy Genevieve Quinn never thought she would be kidnapped from her college campus by a vampire. Or that said vampire would want her help on a science project. Genevieve has no intention of complying, but when an escape attempt turns deadly, it is a vampire that comes to her rescue. Vampire Chad Matthews is an atypical specimen. He's good-looking, in a dangerous kind of way. But that's not what attracts Genevieve… it's the shadows behind his eyes. As Genevieve and Chad team up to find a way to defeat a monster even worse than killer vampires, she discovers that not everything can be explained by science -- like falling in love.
