Nothing happens in this book

Reader, don't waste your time with this book. You might as well stick it back on the shelf, the narrator warns. Or toss it under your bed. You don't need to read it because it looks like nothing happens in this book. But, wait, he's spotted something. There's a trumpet without a trumpeter. And there's a tiny car without a driver. And a baton without a twirler. Maybe if you keep turning the pages, you'll find out who is missing these items. Maybe they are all together, getting ready to do something awesome. Maybe something amazing does happen in this book after all!
