Edit: I should also mention that the sale is currently scheduled to last until the end of this Sunday, the 19th.
There are a lot of good books/authors in the list, but here are some of the ones i like:
L. E. Modesitt Jr. - "Imager Portfolio": Modesitt has a pretty definite style, but so far i think this series is a bit better grounded "Recluse", his other big fantasy series.
Lian Hearn - "Tales of the Otori" - About ninjas in fantasy alternative Sengoku Japan.
Lois McMaster Bujold - "Vorkosigan Saga": I do highly recommend these, but i'm not sure the first chronological book, "Falling Free", is really the best place to start. "Shards of Honor" however does make a good first book.
Lynn Flewelling - "Nightrunner": As long as you're okay with gay elves in your fantasy this is a great series. (Do i have anyone in my friends list who wouldn't be at _least_ "okay" with gay elves? =)
E. E. Knight - "Age of Fire": His "Vampire Earth" books always seemed a little cheesy but fun to me. I've only read the first book in this dragon series so i really don't have much to say about it yet.
Taylor Anderson - "Destroyermen": This is fairly standard "people get sent to another world", in this case it's a pair of WW2 era destroyers getting sent to an alternate earth where sapient lemurs and dinosaurs evolved instead of humans. For the first book the characterization was pretty flat but the world building was cool. Later books improved on the characterization however. It is very gung-ho military, and i've kind of purposefully avoided finding out anything more about the author's political views.
Robin Hobb - "Farseer Trilogy": I would strongly recommend the later "Liveship" trilogy. However i found the protagonists of the first series to be rather frustrating.
Charlaine Harris - "Sookie Stackhouse": If you like vampires and aren't already burned out on the TV adaptation.
Other people have recommended:
C. J. Cherryh - "Foreigner": Keep meaning to read these, have never gotten around to it. Maybe i will now?
Eric Flint, David Weber - "Ring of Fire", aka the 1632 books: I read 1632 off of the Baen free library a long time back. Seemed like a pretty standard "people get sent back in time" story. I generally enjoy those, but i'm not particularly interested in 17th century Germany so i didn't keep up with it.
J. D. Robb - "In Death": I've been told this is a good detective/cop series set a little ways into the future.
Jack L. Chalker - "Saga of the Well World": One of those famous SF series that i read the first book of but didn't get sucked into. Maybe i'll try again.
Neal Stephenson - "The Baroque Cycle": I read the first one of these. It was fine. I'm a bit daunted about delving further into such a lengthy series with the possibility of a "traditional" Stephenson "ending" however.
Mercedes Lackey - "Collegium Chronicles": At least i presume someone would recommend these. I loved a lot of her earlier books but i eventually got kind of burned out and i haven't even touched these, so i can't say much about them.
There are about 90 other authors in the list however, so probably worth checking through if you're at all interested in audiobooks.
