Stanley Hoff has it hard. His overprotective mom thinks she's a witch who can see people's auras; Stanley himself is getting hairier by the minute, his teeth ache, and the moon above him makes him want to howl and growl. But things are not going to get any easier. After a confrontation with a high school bully brings unwanted fame, Stanley's childhood crush Meredith invites him to her Halloween party. Which would be more than fine, except his friend Karen has broken up with her boyfriend and wants to be more than friends. But when Karen turns allergic to sunlight, Stanley has to ask himself, is Karen interested in Stanley as a boyfriend, or as... food?
