I'll compliment Ileia's Star Wars recommendation with a healthy dose of fantasy!
If you like Lord of the Rings, allow me to suggest "Tolkien's true life work", The Silmarillion
. It is considered the bible of his universe, while Lord of the Rings is more of the climax. He spent his entire adult life writing it and still ultimately never finished. Don't let that discourage you, however. Within, I have found stories unmatched in tragedy and triumph carefully crafted with the utmost care. It may be difficult reading, his writing approach mimicked that of an ancient tome using prose and a mythical style. Even with that said, it is highly recommended from me.
I started with Tolkien because his influence has extended to all modern day fantasy. If you want a fantasy novel light on magic, but keen on dialogue and world-building, I urge you to read the series A Song of Ice and Fire
. You may have heard of the fantastic TV show, Game of Thrones, that encompassed the first book in this series. If you've seen the first season though, I would be surprised if you haven't already started reading the rest of the series.
For some great mindless entertainment from the D&D world, you could sample Homeland
from the Legend of Drizzt series.
Also, here's a brilliant flowchart
of NPR's Top 100 SciFi/Fantasy Books.
Here's my favorite quote on books,
"A book is made from a tree. It is an assemblage of flat, flexible parts (still called 'leaves') imprinted with dark pigmented squiggles. One glance at it and you hear the voice of another person - perhaps someone dead for thousands of years. Across the millennia, the author is speaking, clearly and silently, inside your head, directly to you. Writing is perhaps the greatest of human inventions, binding together people, citizens of distant epochs, who never knew one another. Books break the shackles of time, proof that humans can work magic."
