The Hogwash School for Wizards is the most famous school in the wizarding world and Barry Trotter is its most famous pupil. It's been that way ever since J.G. Rollins' Barry Trotter and the Philosopher's Scone broke publishing records worldwide.
But now disaster looms. The movie Barry Trotter and the Inevitable Attempt to Cash-In has gone into final production and the marketing machine at Wagner Bros. is going into overdrive. Hogwash is going to be submerged under a tide of souvenir-crazed Muddle fans, torn apart and sold on eBuy, stone by mossy stone.
The movie must be stopped. Barry, Ermine Cringer and Lon Measly must find a way to defeat the most powerful force of grasping sleazoids the world has ever known: Hollywood.
