Return to Groosham Grange is the second novel in Anthony Horowitz's hilarious and darkly comic fantasy series. The protagonist, David Eliot, a boy sent to the strange Groosham Grange school (where the curriculum includes witchcraft and being monstrous), returns for a new term. The story involves a new and greater threat to the school, forcing David and his friends, Jilly and Jill, to use their unique magical knowledge to defend their eccentric institution. The book is a precursor to the modern magical school genre, known for its humor, clever plotting, and gothic atmosphere, continuing the adventures established in the first book, Groosham Grange.
