Anything by
Robin Hobb (Farseer*, Liveship Traders*, Tawny Man*, River Wilds*, Soldier Son*)
C.S. Friedman (Coldfire*, Magister*, This Alien Shore)
Elizabeth Haydon (Symphony of Ages*, Ven Polypheme*)
Lloyd Alexander (Prydain Chronicles*)
Brent Weeks (Night Angel*, Lightbringer*)
H.P. Lovecraft (At the Mountains of Madness, The Strange Case of Charles Dexter ward, The Thing on the Doorstep, Dreams in the Witch House, The Dream Quest of Unknown Kadath, etc.)
Also, The Last Unicorn and The Princess Bride. Good books, and better movies both.

Series I wouldn't reccomend
The Inheritance (Eragon) series. Go watch the movie, and realize it depicts the only interesting part of the story.
Song of Ice and Fire (Game of Thrones) but you are already reading it.
The Deathgate Cycle, or any Dragonlance books. They aren't terrible, but they aren't good either. They are about as generic as you can get, owing to the fact that they are ancient by modern standards. Darksword holds up pretty well however.
The Sword of Truth series after book 4. The first 2 being vastly superior to the rest of them. It goes downhill in a big way, and keeps going for like 6+ more books. The TV show was actually pretty good.
