No Asimov? and i dunno if this counts but Franz Kafka's The metamorphosis is one of my all time favorites. hmmm let me see.......Mary Doria Russell's The Sparrow was awesome. And i have to say i am not a big fan of Octavia Butler's Wild Seed it was good but the Parable series is my favorite from her and second to that would have to be lilith's brood.
Oh and the Dune hahahaha so middle school but that's what started my love of sci-fi
Great list, though of course it's arbitrary, I'd add Samuel Delany's Dhalgren and Douglas Adams Hitchhiker's Guide To The Galaxy as personal favorites.
And Harlan Ellison is conspicuously absent because he writes short stories almost exclusively, but he's been a major force in Sci Fi for years and years. Check out his Angry Candy, Deathbird Stories or Essential Ellison collections.
I'm a huge fan of Philip K Dick (imagine a headline proclaiming "I LIKE DICK!!!"). HIMAN IN THE HIGH CASTLE, A SCANNER DARKLY and DO ANDROIDS DREAM OF ELECTRIC SHEEP? are faves. Post "new wave" writers like Sam DelanyY and Roger Zelazny are cool.
Heinlein was an original fave, but his later works (like I WILL FEAR NO EVIL and TIME ENOUGH FOR LOVE got too preachy).
For sword & sorcery fantasy. I'm a sucker for Robert E Howard. HIs Conan, Kull and Solomon Kane are great yarns, despite some troubling bouts of racism.
i looove this thread. I'd add The Tommyknockers and The Stand by Stephen King and Kindred by Octavia Butler. Oooh, and speaking of middle school, The Giver and Gathering Blue and anything written by Madeleine L'Engle. Such beautiful, expansive sci-fi.
I loved it. i actually just finished reading it last week (school gets in the way) I love the way she writes. If your into post apocalyptic worlds, Caribbean folklore and strong female leads i think you'll like it too.
