Not into sci fi, but appreciate the rec.
There’s the thing; it all depends on what you think of as SF. There are so many books, novels and stories out there that come under the blanket heading of ‘Science Fiction’ but have virtually no science in, or are really shading into fantasy, and others that certainly have the science in, and are definitely fiction, but don’t have the futuristic content that most would recognise as SF.
Frankenstein is certainly SF, but I’ve seen a good case made for including James Bond. Charles Stross writes books in a wide variety of genres, his Laundry stories are excellent, British undercover spies fighting creatures invading from dark dimensions, basically James Bond fighting Cthulhu!
You really ought to check out William Gibson; he first coined the term ‘cyberspace’ in one of his early short stories, which are collected in Burning Chrome, which is a really good place to start from. His stories tend to the darker, grimy end of things, and if you’ve ever seen Bladerunner, you have pretty much what Gibson’s literary vision looks like. He uses lots of tech, and trade names, real and fictional, that places the stories in a recognisable, future version of our own.
His most recent trilogy I really think you’d like, as it’s pretty much in the present day, but slightly shifted ‘sideways’, involving people who ‘cool hunt’, but are allergic to logos, people obsessing over strange film clips appearing on the Internet that defy interpretation, (written just before YouTube went online), obsessive denim collectors, iPhone controlled helicopter drones and flying penguins and manta rays.
Look for Pattern Recognition, Spook Country, and Zero History. More Noir than SF, but with something of SF in it. Really difficult to categorise, but hugely enjoyable.
