An example of an obscure JK Rowling book: Welcome Back, Potter
Harry Potter gets teacher training, graduates, and gets sent back to Hogwarts to teach. He is assigned a classroom of the worst students in the school, referred to as “sweathogs”, or to be more precise, “warthogs”. See what happens with our future witches and warlocks who have emotional and learning problems, who are unable to manage themselves in a regular witchcraft learning environment. Vinnie Barbarino is played by the son of Count Dracula. Soon to become adapted for television as a sitcom.
