For Sabrina Grimm, living in a community of fairy-tale characters means always being ready for trouble. And something is definitely wrong at her new school. The adults seem to angry, the kids seem too sleepy, and the gym teacher likes dodge ball way 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 Ferryport Landing Elementary has a monster problem. Can the Sisters Grimm solve the crime?
