In what is one of his many children's books, British writer Roald Dahl's George's Marvelous Medicine (1981) tells, as the book's title suggests, George's story. Specifically, the book follows George as he has to deal with his cantankerous and grizzly grandmother, who terrorizes George on a relatively regular basis. When he gets the chance, George mixes up a fantastical potion of ingredients and exacts revenge on his mean grandmother - who grows to an enormous size.
When it was released, George's Marvelous Medicine received mostly positive reviews. After rating it 4 stars, a child reviewer from The Guardian called the book "so funny" and "entertaining" and "hilarious" and tremendous. Another prominent reviewer called Dahl "a true genius" and said that they absolutely loved the book.
