Modern Fantasy, George R.R. Martin is incredible, especially the "A Song of Ice and Fire" series. Then there is Tad Williams incredible series Memory sorrow and thorn (I think... The first novel is the Dragonbone Chair anyway). His Otherland series is awesome too.
Robert Jordan's wheel of time series.
Terry Goodkinds Sword of Truth series starts out very strong, but ends weak. Worth reading the first trilogy though.
Terry Brooks Sword of Shannara Series. Actually, most of his work is good but you might have to struggle through a couple... But definitely read the landover series.
Terry Pratchet is good.
Ursula K. LeGuin has a really old series (Something to do with Tiers in the title...) that are good, but theologically awful.
Ummm... The work Ouroboros is a wonderful old fantasy novel (supposedly the one that started the genre...)
There are TONS of good Fantasy novels. But be aware that there are almost no good fantasy novels for theology. I have read thousands of these books (quite literally) and have never found one that teaches anything approaching good theology outside of Tolkien and Lewis. So be aware of that. Remember the old adage "garbage in garbage out". I continue with this genre because I fell in love with it as a child, and I read a lot of theology to counteract the new-age, modernistic, relativistic, and neo-pagan themes that run through much if this genre.
EDIT: I second the "Dragonriders of Pern" series. Mcaffrey is awesome, and her depiction of the dragons fighting thread tend to be wonderful.
And C.S. Lewis' Space Trilogy is very, very, very well done. Very. Did I mention that it was good yet? Cause its good. But its short. Only complaint is that you can read through the entire series almost in one sitting. But it is incredible.
