A must for Cyber Punk fans, and of course Blade Runner fans is "Do Androids Dream of Electric Sheep" which is the novel by Philip K. Dick on which Blade Runner was adapted from.

Anyway I picked it up again for the first time in almost 5 years and just finished it. I must say it is by far one of my favourite reads and even today it holds its own against modern sci-fi books, truely one ahead of it's time.
