Hmm.
Lots of cool "fantasy-inspired" D+D/RPG reading lately. (I'm a rabid bibliophile, especially of the fantasy genre!!)
Here's a few:
1) Knight of the Black Rose: 2E Ravenloft. Arguably the best known Ravenloft novel, featuring Lord Soth pre-exodus. (Note that almost all the RL novels are worth reading; "Carnival of Fear" is my second favorite of the series.
2) The first "Dark Elf" trilogy: Really absoring and innovative. (But ignore everything that came after!)
3) The Black Company series: The RPG is a good adaptation, but you need to read the books to get the full expereince.
4) "Fire+Ice": By James Alan Gardener, for the Planescpae setting. Available for free here: (
http://www.ralf.org/~krlipka/ps/fiction/local.html) One of the coolest RPG-novels I've read. I've been touting this for years, and I'm STILL bummed that the series isn't going on.
5) "Eric of Melnibone" saga. (First 6 books, anyway!!)
6) Dragonlance Chronicles and Dragonlance Legends series.
And obviously, "Wheel of Time" and "Game of Thrones" go without saying.
There's lots of other stuff that inspires me to play D+D, but isn't necessarily connected to a specific D+D setting:
1) "Memory, Sorrow and Thorn": No D+D discussion is comlpete without Tad Willaims
2) "Wars of Light and Shadow" by Janny Wurts. Extremely complex and thought-provoking, filled with "shades of grey".
3) "Perdido Street Station": More steampunk than fantasy, but still very D+D-esque.
4) "Nighwatch": The idea of two warring supernatural factions keeping tabs on each other and enforcing neutrality is very exciting, to me.
5) "Godslayer Chronciles" by James Clemens. Only two books out so far, but very engrossing nonetheless.
6) 3 Hearts and 3 Lions: Exemplary instance of a paladin.
7) "Guardian of the Flame" by Joel Rosenberg. (Sure, it's one of those "Modern day kids transported to fantasy world stories", but I still have a soft spot for this series.)
