Monstrous Regiment by Terry Pratchett. I think that would be a great book to adapt.

I'd like to see Ian McDonald's River of Gods or The Dervish House made into a 10ep series. They're both fantastic cyberpunk books and would make excellent TV.

Also, absolute long shot here but I'd love to see Iain Banks' The Culture series adapted for premium streaming with a Foundation series budget.

Remove most of the muscle porn from it, which wouldn't be hard since the main characters are all essentially superheroes, and the entirety of The Deathworlders, the canon parts of Salvage, The Xiu Chang Saga, and Humans Dont Make Good Pets.

The Jenkinsverse has a ton of potential there.

ETA: also a documentary narrated by David Attenborough, based on Alice in Sunderland.

The Girl from Earths End By Tara Dairman

It's like Harry Potter if you replace magic with botany, and JK Rowling's shittiest values with the opposite of that.

Also fair warning it will make you cry

Dredd could be a whole franchise

I would love a faithful adaptation of Worm, but I don't think it could ever do the series justice.

Children of time, but as a scifi miniseries.

Magic Kingdom of Landover

The Aubrey/Maturin series by Patrick O'Brian - yes, I know there's been a movie (Master & Commander with Russel Crowe and Paul Bettany) but the series is much richer and deeper than any single movie could be.

Also, Robin Hobb's Realm of the Elderlings series. Concentrate on the Fitz storyline, maybe give the Liveship series a miss.

Not a book exactly, but East of West would make for some great narrative and world building.

John Varley Gaia Trilogy.

Foundation.

Michael Morecocks Eternal Champion saga. Great candidate for a Netflix animation

Lord Valentine’s Castle series by Robert Silverberg

There's a book called Robopocalypse where an AI gains sentience and then takes control of basically all robotics/anything connected to the internet to take over the world and I'd love to see that as a mini series.

Snowcrash

The Gap Cycle series

LOL IDK how you would do the first book or even touch on that part of the books (because it makes them very very hard to suggest let alone reread) but once you got to the singularity bomb at the science space station deep in a dense asteroid field.... I wanna see that part. The emotions that the story creates in the characters is pretty primal and believable. Its an interesting story how each of the main characters goes through the same level of violation but in different ways

Haroun and the Sea of Stories

All the Muderbot series

Old Man’s War series
