The town of Ferriport Landing is inhabited by both people and fairy-tale characters, and therefore Sabrina and Daphne Grimm are ready for anything. But something completely strange begins to happen in their school - schoolchildren sit half asleep in class, quarrels break out perfectly, and only bouncers are allowed in physical education. When one of the teachers is attacked by a giant spider, Sabrina and Daphne begin their own investigation. Almost immediately, it becomes clear that monsters are involved. Will Daphne and Sabrina - descendants of the great Brothers Grimm - get to the bottom of it? Michael Buckley is the author of a string of New York Times bestsellers and acclaimed television series. The Grimm Sisters series of books appeared in 2005 and became an international bestseller.
