No, it won't. I'm especially sad that this, like so many OOP guides before it, did not go into how it interacts with data structures and bigger picture stuff. It had the perfect chance to do that as it could have made a Catalog class and then had a discussion about what belongs to that and what to the books. Instead it started to abstract on author, in the stupidest way possible (no, no one will ever look up a book using the author birth date).
