I love reading drama. What is your favorite genre?

I wonder when people started reading for fun.
I believe people have been reading for fun for quite some time. If you look at some of the classic writing, most of it had the purpose of being read leisurely. Even though they were trying to get a point across.
Is there a "most famous" author? 
Earnest Hemingway is one of the most famous authors in the 1900s. 
Are there any book clubs I could join and get a new book every month?
I don't know about any book clubs, but you can always go to a library and check out as many books as you could ever want for free. There is so much wisdom and knowledge in libraries.
