“The Lost Boys” by Orson Scott Card.
I’ve read loads of SciFi but on that list, only 1984 and Dune.
Saw a few others listed that brought back memories...
Stranger in A Strange Land
Lots of Heinlin and Bradbury, no way I could list them all
Farenheit 451
Clockwork Orange
Ringworld
Riverworld
Martian Chronicles
Childhood’s End
The Mote in God’s Eye
Animal Farm ( the other Orwell book often overlooked)
Hitchhiker’s Guide to the Galaxy
Restaurant at the end of the Universe
So Long and Thanks for all the Fish
the other 2 in that series, can’t remember the names, hilarious
Another humorous series is Roger Lynn Aspirin’s Myth Adventures series, hilarious books.
Myth Adventures
Another Fine Myth
Myth inc Link
and so on, plus Thieve’s World is a compilation by different authors, based on the idea of a Thieve’s World that was a spin off of the Myth Adventures series.
Loads of Philip Jose Farmer and Kurt Vonnegut
One everybody should read, takes under 2 hours, Illusions by Richard Bach. My all time favorite book. Get it, read it...dozens of times...I still pull it out and read it now and then and I read it the first time 30 years ago. I don’t care what kind of reading you like READ IT...
Tolkein’s Hobbit books
Loads of Roger Zelazny, great writer, several Peirs Anthony books, another great writer.
If you’re into swords & sorcery a little, my all time favorite is Zelazny’s Amber series.
What else...I can’t remember ‘em all, I’ve been a heavy reader since age 5, probably read hundreds of sci fi along with loads of educational stuff, college textbooks - Geology, Archaeology, biology, Anthropology, Sociology have a good Zoology nook now but haven’t started on it, just about anything...
