This is a book about a boy called George who lives wih his family, including his mean Grandma. She is always unkind to George when his parents go out. George decides to make a nasty medicine for his Grandma and puts in a whole list of revolting things, including shampoo, brown paint and animal pills. Grandma takes the medicine and starts to grow to a ridiculous size.
I liked this book because it had a good adventure and was funny. My favourite bit was when the medicine went wrong and Grandma shrunk so much that she disappeared. I think that this book would be enjoyed by people who like Roald Dahl and funny books. Other Roald Dahl books you might like are Matilda, Fantastic Mr Fox and Charlie and The Chocolate Factory.
