This book is a little strange as you can see from the picture I have drawn. The main character lives in a world where everyone loves books and loves to write book. There are stores built on top of levels of catacombs of books. Some books are dangerous. They can harm and kill you.
This picture above is of the main character after listening to a concert of species of ..."alien" that live in the world. There musical voice can make people do stupid things. This concert made every one buy the most boring book imaginable. They don't even realize they are buying them until they get home with the books.
