Would you be down to follow a Dark Elf main character as he survives his brutal dark elf society to become ome of the greatest swordsman and hero?
If so, Homeland by R. A. Salvatore
Nothing's really 5th edition specific, but D&D has a number of official settings that all have their own lore. The "default" setting for 5e is Forgotten Realms, which you can read about in decades of novels or play in through decades of video games in addition to all the pre-made D&D campaigns set in the region. There's also a ton of material for other settings like Dragonlance, Greyhawk, and Eberron, although there's not as much as for Forgotten Realms, especially if you're looking for 5e specific material.
I love most of the Forgotten Realms books. RA Salvatore is my favorite author, his Dark Elf trilogy is well worth the read. Establishes the back story of arguably the single most well known character in all of DnD, Drizzt Do'urden. Great stories, cool characters, and leads into a sprawling series of books.
Same author also did SpearWielder's Tale. Which is the story of a factory worker that finds himself transported to a mythical land that, supposedly, is the inspiration behind Tolken's universe. Very Amusing read. Highly recommend.
I also really liked the Horus Heresy series from Warhammer 40k. Good introduction to that world and the fall of the emperor's favorite son to Chaos.
I also enjoyed The Year of Rogue Dragons Trilogy. Features a half golem dragon hunter as the main character.
Finally, The Crimson Shadow series is really good. Kind of a high fantasy version of Robinhood.
Also, Game of thrones is good. . . but very, very depressing.
If you like fantasy then I'd definitely suggest Homeland by R.A. Salvatore
Raptor Red is also a great book.
If you're more into sci-fi then Snow Crash is a great pick.
I really like Homeland: The Dark Elf Trilogy By R.A Salvatore but only the first three, after that they really go downhill in quality http://www.amazon.com/Homeland-Trilogy-Forgotten-Realms-Legend/dp/0786939532/ref=cm_lmf_tit_1
