Lexi knows there's something weird about Julie, the new girl at Edgar Allen Poe High School. Julie was practically drooling over a worm in biology lab. Then Lexi swears she saw Julie snatch a fly out of the air in homeroom—and eat it! Now Julie is after Lexi's best friend, Fitz. And Fitz is totally falling for her. He loves everything about Julie—especially the cookies and candies she brings him. Lexi suspects Julie is fattening Fitz up for a feast—and that "he's" going to be the main course.
