Yes, it is. Go read them already
David Eddings: pretty much anything;
Pawn of Prophecy and
The Diamond Throne are the starts of two different series of books.
The Redemption of Althalas is a stand-alone work, if you don't want to dive into any series.
Alan Dean Foster: The Flinx series introduces the Humanx Commonwealth, the setting for most of his work. The Ice Rigger Trilogy, The Damned trilogy, and I'm sure the Spellsinger series are all good (I haven't read Spellsinger yet -- can't find it -- but I'm confident in its quality).
The I Inside,
Mad Amos, and
Kingdoms of Light are good standalones.
If ya want something harder, tackle Gene Wolfe's
Book of the New Sun.
Edit: Wow. Judging by the lack of responses to this, you'd think Eric had just banished this post to Limbo. Anyways...
Issac Asimov certianly should be mentioned; some of his works may feel a bit dated at this point, but in general he's worth reading. The Foundation Series is generally good (I didn't care for
Foundation's Edge and
Prelude to Foundation).
Larry Niven's Ringworld series is worth a look.
Robert Silverberg's is also worth a look; most of his books are stand-alones.
I don't care much for Terry Brooks, but I liked the Scions of Shannara books.
Oh, yeah -- Roger Zelazny. The Amber series is gold.
Check out the local library; you may find a surprisingly large selection of sci-fi and fantasy there (heck, the local library near where I live actually outshines some of the bookstores in this area).
I hope that helps.
