A Memory of Light question

Mistborn - The main trilogy is complete and has a real, definitive ending. There's also a 4th book, but it takes place 300 years after the first 3 books, with a new story and new characters. It will eventually spawn a new trilogy. I highly recommend it. It's incredibly original, with a great story and memorable characters. It's also quite easy to read, while still being well written.

The Wheel of Time - The last book just came out (and I'm currently reading it). This series requires a lot of dedication from the reader. There are 15 books in it, all long, with an insane amount of named characters. But it's so worth it. One of the best, most epic series I've ever read.

The Black Company - Technically, it isn't over because Glen Cook plans to release other books. However, the saga is currently composed of 9 novels and a spin-off, and they cover 40 years of history. The last book gives a solid ending to the main characters' storyline, and I think it can be considered a complete series as it is. I really love these books and I wish they were more popular.

The Dark Tower - This series is both Fantasy and Sci-fi, with quite a bit of Horror in between. I loved it.

The Lord of the Rings - The classic choice.

i would suggest the Drenai, the Rigante and the Hawk queen series by David Gemmell. though the hawk queen is only 2 books.

I like Jim Butcher's Codex Alera - it's a bit lighter than some of these, but very entertaining. And I second the Mistborn trilogy recommendation.

I'll second Brent Weeks' Night Angel trilogy and Joe Abercrombie's First Law Trilogy. His one stand alone book, The Heroes is one of the best things I've read but if you want to understand all the easter eggs you have to read the First Law Trilogy and Best Served Cold to get them.

If you're interested in a longer investment, Terry Goodkind's Sword Of Truth series is quite good for the most part. His later books get a bit preachy and repetitive but the first six are stellar. By then you need to read the rest just to know how it all ends.

I too enjoyed Memory, Sorrow, And Thorn and also the Farseer Trilogy. Robin Hobb has written more books in the same world as Farseer which consist of two more complete trilogies(Liveship Traders and Tawny Man, respectively) and a soon-to-be-finished quartet(the Rain Wilds Chronicles). All of these are excellent, in my opinion.

If you wanted to go a bit more old-school, Fritz Leiber wrote a great series of sword-and-sorcery short stories which were collected into the Fafhrd And The Grey Mouser Saga, a seven book series(septet?) of hilarious, unconventional fantasy. Also, if you're into picaresques, check out the Dying Earth series by Jack Vance, which has recently been collected in an omnibus volume entitled Tales Of A Dying Earth. Great stuff. And of course I would be remiss if I didn't mention the Earthsea series by Ursula K. Le Guin. Although I haven't read them all, I have read the first three, and I thought they were brilliant.

Definitely: the Wheel of Time series
The Codex Alera
The Dresden files (fun and nerdy)
Belgariad, but the Malloreon is basically the same thing
Mistborn
the Stormlight Archives, but that's only started

I highly reccomend The Kingdoms of Thorn and Bone by Greg Keyes. One of the best I've read and I've read most. I'll admit the last book was a little of a let-down but the series is still great.

Robin Hobb's Assassin trilogy, and her Tawny Man trilogy (the characters from the Assassin books are also the primaries in Tawny Man, but they really are two separate trilogies--read the Assassin series first). I enjoyed her Soldier Son series, too, but not quite as much. And I tried but failed to get into the Ship of Magic, etc. I think it's the first-person point-of-view that she uses in the ones I liked.

A much older series that I really enjoyed is Shadow Moon, Shadow Dawn, Shadow Star by Chris Claremont/George Lucas. They are a follow-on to the Willow movie, though very different.

If you like some romance with your fantasy, I loved Shana Abe's dragon books. The Smoke Thief, The Dream Thief, etc (I think there are like 7 or 8). They don't strictly have to be read in order (I know I didn't), and while the characters are inter-related, there are different primary characters in each book. Beautiful and fun to read.

I like the Century Quartet Series.And the oracles of delphi keep series

Pick any of L.E Modesitt Junior:

1. The Saga of Recluce
2. The Corean Chronicles
3. The Imager's Portfolio

In each Magic is just an Innate "Talent" but in each series, L.E M Jr Presents a different world. All low Tech but not all at the same level. Talent is sourced differently in each yet in all it has a direct link with the planet in which they live.

Good versus Evil, particularly in the Saga of Recluce is not as cut dry as in most epic fantasy books. It wanes back and fro between the White and the dark forces (incidently the Dark are the forces of Order, and the White is the force of Chaos, but neither is evil or Good, they just are two extremes of the same spectrum. Throughout the series, the hero (always good, but with knucklehead faults) is sometimes a White Mage of Chaos or a Dark order mage. But everytime the hero or heroin is a rogue, a loner, a non-conformist with the Status Quo. Every time He/she ia a Brave Agent of change who always has to pay a price for the heroism. It keeps things pretty mixed up. The author jumps back and forth along the chronological line of the PLanet, sometimes giving life to a character of Legend mentioned in passing as a heros of Old in one of the previous books. Sometimes, the book is a descendant of the previous book's heros, but their time line is several centuries apart. Whenever a new volume is published on the Saga of Recluce, you only now in which world you will end up, but you never know in which continent nor in which time frame in the history of that planet. It keeps things exciting.

The latest series of the Imager's Portfolio is similar in that fashion. The first trilogy takes place centuries after the events of the second trilogy. In other words, the latter trilogy is the prequel of the former.

The Riyria Revelations - Great read!
Malazan Book of the Fallen - Huge world, Huge story line.
Wilbur Smiths Courtney series, Starts with When the Lions Feed.

Belgariad/Mallorean + Prequels
Mistborn
Elenium/Tamuli

Some of the best available series have already been listed. I would add Memory, Sorrow and Thorn by Tad Williams, The Riftwar Saga by Raymond Feist and The Riyria Revelations by Michael J. Sullivan. In three weeks the last book in The Demon Cycle trilogy by Peter V. Brett will be released. That is an excellent series as well.

I particularly like N.K. Jemisin's Inheritance Trilogy for something a little different. Guy Gavriel Kay's Fionavar Tapestry is worth a look too. Plus he does some good standalone novels. I also highly recommend Tad Williams' Memory, Sorrow and Thorn if you've not read them yet.

The Night Angel Trilogy by Brent Weeks is really awesome. It's a anti-hero assassin fantasy with multiple magic systems in the world and it's cool to see how the world expands from one city to countries throughout the series. His lightbringer series is also looking really good waiting for the third book to come out.

Well, the First Law trilogy comes to mind as being alike to the Wheel of Time series, if a bit darker perhaps. Oh! and the Farseer trilogy as well, though i have heard that the story goes on beyond that trilogy, but i have not gotten around to reading beyond it yet, so i can't really comment.

Of course there are plenty of series beyond them, but none i remember being alike to WoT at the top of my head.
