Everyone at school can't stop talking about how hot Meredith Willis's new next-door neighbor, Adrien, is. But Meredith can't help but think there's something strange about the cool, sophisticated new guy, and those sunglasses he constantly wears are the least of it. Every time he's around, Meredith sees things—terrifying things that nobody else seems to notice. And when she dares to sneak a look into the windows of his house, she sees something in the cellar that makes her believe that Adrien might be more than just a creep—he may be an actual monster. But her sister, Heather, doesn't share Meredith's repulsion. Heather believes Adrien is the only guy who really understands her. In fact, she may be falling in love with him. When Adrien and Heather are cast as the leads in the school production of Romeo and Juliet, to Heather, it feels like fate. To Meredith, it feels like a bad omen. But if she tries to tear the couple apart, she could end up the last place she'd ever want to be: the cellar. Can Meredith convince her sister that she's dating the living dead before it's too late for both of them?
