David Eddings: the
Belgariad and/or the
Mallorean.
Ursula K. LeGuin: the
Wizard of Earthsea sequence.
Raymond E. Feist:
Magician,
Silverthorn,
A Darkness at Sethanon.
Raymond E. Feist and Janny Wurtz:
Daughter of the Empire,
Servant of the Empire and
Mistress of the Empire.
Don't bother with the "Shadow of a Serpent Queen" and suchlike titles, though, in my opinion.
Raymond E. Feist:
Faerie Tale. It's unrelated to the above titles.
Peter O'Toole: The
Modesty Blaise series.
Orson Scott Card:
Ender's Game,
Speaker For The Dead,
Xenocide and maybe
Ender's Shadow but maybe not.
Anne McCaffrey:
Dragonflight,
Dragonquest,
Dragonsong,
Dragonsinger,
Dragondrums,
The White Dragon,
Dragonohforsod'ssakeenoughalready,
Crystal Singer,
Killashandra,
Crystal Line,
To Ride Pegasus,
Pegasus in Flight,
Pegasus in Space,
Tower and Hive,
Lyon's Pride,
Damia,
Damia's Children (not necessarily in that order).
Laurell K. Hamilton: the
Anita Blake series, or at least the first few of it:
Guilty Pleasures,
The Laughing Corpse,
Circus of the Damned,
The Lunatic Cafe and
Bloody Bones. They got a bit predictable a over-raunched as she went on and switch from out of her depth and clinging on for dawn to loafing in a huge silk-decked four-poster bed with her pet ancient vampires and alpha male werewolves. Don't bother with the Meredith books,
A Kiss of Shadows and its followers.
Terry Moore:
Strangers in Paradise. Good luck getting the full set of hardbacks, but you can get a full set of the pocket-sized ones [http://www.strangersinparadise.com/store.html].
Garth Ennis: Preacher [http://www.amazon.co.uk/Preacher-Graphic-Novels-in-order/lm/211UIUN3PAQKM].
Wilbur Smith: too many to list [http://www.wilbursmithbooks.com/novels/bibliography.html]. They get a bit too similar if you read too many of them, but they're good.
River God was rather different, for reasons explained in a note towards the end of the book.
Shout At The Devil is singularly horrible.
Wild Justice is a bit too much of a Hollywood action flick and not enough of a book. You'd probably do better to stick with the older stuff:
A Falcon Flies,
Men of Men,
The Angels Weep,
The Leopard Hunts In Darkness and
Triumph Of The Sun and
When The Lion Feeds,
The Sound Of Thunder,
A Sparrow Falls,
The Burnign Shore and so on, which overlap somewhat in time.
Robert Ludlum: several books [http://www.amazon.co.uk/s/ref=nb_sb_noss?url=search-alias%3Dstripbooks&field-keywords=Robert+Ludlum&x=0&y=0&ih=10_2_0_0_0_1_0_0_0_1.44_212&fsc=-1], including some whose titles you may recognise from recent film publicity.
Alistair Maclean:
Where Eagles Dare,
When Eight Bells Toll,
The Satan Bug,
Ice Station Zebra et cetera. I want to fly this route [http://www.youtube.com/watch?v=8XKGhG0W0LQ]!
Terry Pratchett:
The Colour of Magic,
The Light Fantastic,
Wyrd Sisters.
Mort and
Pyramids,
Truckers,
Diggers and
Wings and
Only You Can Save Mankind.
Terry Pratchett and Neil Gaiman:
Good Omens.
William Gibson:
Neuromancer.
Tom Sharpe:
Wilt,
Wilt On High,
The Wilt Alternative.
James Herbert:
The Dark,
Rats,
Lair,
Domain,
The Fog and some others are good but some of his other work is pretty lame by comparison.
Stephen King:
IT, Christine and Bag of Bones but not Misery or Cujo.

On the other side, I advise you to avoid anything related to "Magic Kingdom For Sale Sold", "Titus Groan" or Terry Brooks in general, actually.
