Lexi knows there's something weird about Julie, the new girl at Edgar Allan 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.
