I used to like Greg Bear around that age.
I’ve got a few I’m more than happy to pass on to him
I know it’s not SF but my 14 year old demolished The Belgariad and The Mallorean series by David Eddings while telling us she only likes SF and not Fantasy.
That’s the thing fantasy he couldn’t care for
But he’s a teen so no real rules , I just want him to keep enjoying books and where they take you.
I don’t read as much as I’d like to but the love is there
This ^^^.
As I recall a combination of of-its-time (1950’s) realism and some borderline frightening stuff (The Chrysalids has some unpleasant moments). That said, I read everything of his I could lay my hands on.
Think I was around 12/13 when I read the Martian Chronicles by Ray Bradbury, had me absolutely hooked.
E E Doc Smith. The Classic Lensman series. Very early hard sci fi.
At that age it was Asimov, Tolkien Lord of the Rings decades ago.
Ray Bradbury The Martian Chronicles? Can’t remember how old they are.
As a laugh The Stainless Steel Rat and the Discworld series.
The genre continues with some great new writers so it can last a lifetime and never grow outdated.
The Kim Stanley Robinson Mars trilogy is a good read.
Some of Clifford Simak’s stuff might hit the spot. I enjoyed it when I was 12 or 13.
Some great suggestions here, can’t really go wrong with Clarke and Asimov.
The Expanse series of books is excellent and if you have Prime the TV series is also great, although it messes around with the timeline from the books a fair bit towards the end.
Stanislaw Lem: Tales of Pirx The Pilot
I’ve loved every Iain M Banks book that I’ve read
Yep you’re never too young to start reading about the Culture.
Against a Dark Background is my favourite Banks book (not Culture, though)
Definitely up there, bagged a cheapo kindle offer on it recently fer peanuts.
Excession is prolly me fave. Currently re-reading the Culture series in correct sequence for the main novels with the exception of “Inversions.” Currently on “Matter”
It’s a bit of an anomaly as it’s a standalone book.
All the Culture books are great, Use of Weapons is probably my fave.
Of his non-sci-fi stuff, The Bridge is one of my favourite books ever.
The Stephen King Dark Tower series is awesome as well, though probably more fantasy than pure sci-fi.
Most of China Mieville’s stuff is really great as well.
Love the Bridge, Canal Dreams also. So many classics, been hooked ever since The Wasp Factory first came out.
Yeah, a real talent, sadly missed.
