What are the 3 motto of book called wave?

There isn't a book called "Wave" that I'm aware of with three specific mottos. It's possible you're thinking of a different book, or a specific edition or translation of "Wave" might have mottos, but I'd need more context to help you.

Could you please provide more information about the book you're referring to? For example:

* The full title of the book: Is it "The Wave" or something else?

* The author of the book: Who wrote it?

* Any other details about the book: Is it a novel, a nonfiction work, or something else?

With more information, I can help you find the mottos you're looking for.
