Since I just agreed with the OP in my first post, I'll add some of my own...
Mythago Wood by Robert Holdstock is certainly one of the fantasy books I've enjoyed the most. Although there are more books following on from it, it can certainly be read on its own.
Ash: A Secret History by Mary Gentle is another which stands particularly tall in my memory.
I also have to second Feist's
Faerie Tale, which I absolutely loved. It's been a while since I read it too, but I'm sure it will still deliver.
