LORD OF THE RINGS!!!!!! <3 The Hobbit and after you've read those, the Silmarillion and histories of Middle Earth, the children of Hurin, and so on and so forth until you've read everything Tolkein has ever written XD And, for non Tolkin literature There's also The Prince of Thorns (part of a trilogy. I haven't read the rest of the books but the first one was fantastic!) The Name of The Wind (reading it now. So far, it's live up to the hype) And for non fantasy books: The Shadow of the Wind was absolutely fantastic! Definitely in my top 5 favorites.
Harry Potter series Shadow Falls by C.C. Hunter is super good The Long Walk by Stephen King Ghost by John Ringo The Luxe series (cant remember the author) Nine Lives of Chloe King Percy Jackson Witch and Wizard Girl With the Dragon Tattoo
