the Harry Potter serie for people who like fantastic books, or percy jackson. I got really absorbed in memoirs of a geisha and life of pi, those are really good. Paulo coelho's books if you like something a bit philosophical that makes you think with beautiful words. As for old novels, Dracula is amazing.
