For Sabrina Grimm, living in a community of fairytale characters means always being ready for trouble. And something is definitely wrong at her new school. The adults seem too angry, the kids seem too sleepy and the gym teacher likes dodgeball far too much. Of course, her little sister, Daphne, is having the time of her life. (Who wouldn't with Snow White for a teacher-she's so good with little people!) But when Sabrina's teacher, Mr Grumpner, is found dangling in a giant spider web, even sunny Daphne's convinced that Ferryport Landing Elementary has a monster problem. Can the Sisters Grimm solve the crime?
