Adam Lyon is a little misunderstood. Literally. Ever since his name was mistyped at the school admissions office, he's been the only human student at Charles Darwin Middle School, where the golden rule is "Do not eat the other students." And at CDMS, things are wild: Stalking class is required, the school bully has a dorsal fin, the cafeteria serves bug soup, and Adam's best friend is a spider monkey named Jake!
