William Gibson's Sprawl Trilogy. Image from Wikimedia Commons.
Cyberpunk is a science fiction subgenre which tends to be set in the near future and focus on technology, hacking and the interaction betweeen human and machine, and have a noir flavour to it. William Gibson's "Sprawl Trilogy" (Neuromancer, Count Zero and Mona Lisa Overdrive) and Neal Stevenson's Snow Crash are some classic examples.
I'm not sure if Maggie Gee's 'The Ice People' would count'. It is set in the near future, and explores the different kind of technologies that we have. There world then enters an ice age, and we revert back to a very primitive like state.
Neuromancer is probably my favourite. I revisit it every few years. Johnny Pneumonic is also an interesting story, and may have launched the weird sci fi trope of junkie dolphins which oddly crops up a few times in different books.
I also enjoyed Snow Crash. It's kind of silly but it has this mad energy to it, as so many debut novels do, like the author thought he might never get another chance at a novel so he'd better put in every cool thing he could think of.
How could I forget Do Androids Dream of Electric Sheep? It's maybe one case where the movie adaptation (Bladerunner) is actually better, but the book has its charms. My favourite line is "my schedule calls for two hours of self-accusatory despair."
Can't say I have come across many cyberpunk books (I love it when I do, will be checking out Gibson now). I have read the Young Adult Paris Pliess novels - the first one is called Nylon Angel. Loved it!
Gibson is always worth a look. For my money, the Bridge trilogy (starting with Virtual Light) is even better than the Sprawl books - a bit better organised, and a bit more tightly plotted. I also think that Pattern Recognition, despite being set in 2002, is basically a cyberpunk novel. Gibson is on record as saying that we live in a science-fiction story now - the only question is whether or not it's a dystopia.
