With intriguing prompts, readers will discover that the book can be: A secret message—tear out a page, write a note on it for a stranger, and leave it in a public place. A recording device—have everyone you contact today write their name in the book. An instrument—create as many sounds as you can using the book, like flipping the pages fast or slapping the cover. This Is Not a Book will engage readers by having them define everything a book can be by asking, “If it’s not a book, what is it then?”—with a kaleidoscope of possible answers.
