my favorite books would have to be the Powder Mage trilogy by Brian McClellan

I'd probably go with Jane Austen's "Pride & Prejudice." That is the book that turned me onto literature vs books for kids and teens.
The one person who said "Les Miserables"... that is also a good one. Also love "The Count of Monte Cristo" and "The Great Gatsby." I could name many more, though.
This is a pic of one of many places I have books stashed, lol (most of the books you can make out are from my race/ethnicity phase):
