If you are speaking of Brandon Sanderson, his Way of Kings (Stormlight Archive) is a very decent one to look at. Brandon Sanderson is a great middle ground for any reader as he has everything that most authors wish they had. A new take on writing and world building that can even make cliches feel new and inviting, as well as very good character progression. His novellas are amazing reads and I haven't found any books that proves otherwise.
Steven Erikson's Book of the Malazan Fallen series: (Completed)
Very detailed and character rich environment. Just as dark and brooding as George R.R. Martin, but a different take in story telling. As Martin focuses more on an immediate point of view perspective (inside->out), Erikson is more of a switch (outside->in) in how focus towards the plot goes. Erikson is actually further reaching and encompassing than Jordan's masterpiece but is also technically harder of a read. I personally found it amazing, but the first novel, Gardens of the Moon, might be a hard book to start on. I suggest it heavily as a favorite, but such points are subjective.
Series completed, one novella series that acts as a standalone, another series by his co-creator of the world in question, Ian C Esslemont, and an extra trilogy (currently writing) that delves into the past by a few thousand years. The quality of the books holds true throughout.
Patrick Rothfuss, Name of the Wind (Incomplete 2/3)
He has two books in the trilogy out, and the only thing you will hate me for suggesting this is when you are impatiently waiting for his third book once you read the first two. It is a magnificent book that completely belies the fact that it was his first. Read the reviews and you will see what I mean. It is like a high rated IMDB movie, it took the attention of many for very decent reasons. Good story, inventive setting, characters and magic systems, and very nice pacing and progression.
Jim Butcher, Codex Alera series (completed)
Writer of the well known Dresden files. His first two books of the Dresden files were hard reads as he was learning and progressing as a writer. In Codex Alera, he took everything he learned and delved into a sensible fantasy story that was well fleshed out and very decent. A very good series to read and enjoy.
Adrian Tchaikovsky: Shadows of the apt (Incomplete, but well into the series)
British author with a decent number of books in the series, but not enough to stop you from trying. Very decent story with good characters and an interesting concept. It is not my absolute favorite, but the series was very enjoyable
I have more I can suggest, but I think I will stop for now. Hope any of them picks your fancy.
