Ok, maybe this is not a literature question after all but it's about books so I thought..... And OK, maybe it's still not a good thing to start a sentence with OK but who gives a s**t, really? Question is: I've been through the Sheckley stuff, the Asimov-classics and all the Niven/Pournelle masterpieces twice now ('Lucifer's Hammer' being my favourite or favioret, whatever you prefer) and am now desperately looking for something comparable and a little bit more recent. any recommendations?
Okay, its not recent but have you had a bash at the Dune series, I last read it as a kid and am bashing through it again. Try "the people" books by Zenna Henderson, the anthology is called "Ingathering" Anne McCaffery's Pern series is worth a look, also her "To ride a Unicorn" series about telepaths, and her "The Ship who" series about disabled people who put on space ships instead of wheelchairs. Lastly for a vintage laugh, take a look at the Gray Lensman books.
I'd recommend: Peter F. Hamilton (especially the "Night's Dawn") trilogy, Stephen Baxter, Greg Bear (though he tends to have a problem with satisfactory endings IMHO), Michael Marshall Smith (especially "Spares" and "One of Us"). I'm sure there's more but lack of space means most of my collection is in storage :-(.
If you haven't read Iain M. Banks already, his sci-fi books are brilliant - try Consider Phlebas, Player of Games, Inversions and Use of Weapons. Maybe also look into the books of Vernor Vinge and David Brin.
Definitely the "nights's dawn" trilogy,also Peter F. Hamilton's recent book "Pandora's Star". "the saga of the seven suns" series by Kevin J. Anderson,and just about anything by Stephen Baxter.
My two sci-fi favourites are: "Enders Game" by Orson Scott Card (and if you like that you could read the whole series) and The Gap Series by Stephen Donaldson
Personally I'm a fan of Lois McMaster Bujold's "Miles Vorkosigan" series about a sort of intergalactic (but midget) James Bond and am pretty keen on David Weber's "Honor Harrington" series (even if they are a bit of a rip off of C.S.Forester's "Hornblower" series) though they can be fairly variable. Both might be (somewhat condescendingly) described as Space Opera, to give an indication of the tone.
Give Kim Stanley Robinson a go - "Escape from Kathmandu" is very entertaining and funny, particularly if you are a mountaineer, and "Antarctica" is an intriguing slant on future tourism.
