There are many famous Johns throughout history, each with their own works. To help me understand your request, could you please specify:
* Which John are you referring to? For example, John Locke, John Milton, John Steinbeck, John Green, etc.
* What kind of books are you interested in? Are you looking for the general themes of their writing, specific genres they worked in, or a list of their most famous works?
Once you provide me with more information, I can give you a more accurate and helpful answer.
