It's likely that you're asking about two books that John has read, one of which is Brave New World. However, we don't have any information about John or his reading preferences.
To give you a better answer, can you please provide more context? For example:
* Who is John? Is this a character from a book, a real person, or a fictional one you created?
* What kind of books does John usually read? Do you have any clues about his interests?
* Is there a specific reason you're asking about these two books?
With more information, I can help you figure out what other book John might have read alongside Brave New World. 😊
