Future XXI century and dust. Case is a hacker, hacking into systems to steal data and sell them. Or rather was his last employers who mutilated him his neural connections to deny him access to the "matrix." Converted into a barfly and junkie, it comes one day find it in its Japanese ghetto offer him a contract. Down the road: new pancreas, new life. He immediately jumps on the occasion, ignoring what hornet's nest he sets foot. Neuromancer was the effect of a small bomb when it was released, winning the Hugo, Nebula and PK Dick at once. William Gibson proposes a new vision of SF, most immediate and credible than was previously. Exit the stories of robots, spaceships: the future here is close, urban, violent. Gibson Neuromancer develops in anticipation of an advanced internet (the matrix) and inevitably comes to addressing the virtual realities, even if it is only superficially. It also describes the corporation as an autonomous being, enormous and perverse. For all these reasons, we are dealing with a visionary novel, which also spread to all media of the imagination. There are now so many works that have their references in this book: the manga (Ghost in the shell), film (The Matrix), role playing (Cyberpunk 2020, Shadowrun), everything goes. It is striking to see what place does the technology in Gibson's world. Unlike Terminator, Matrix and Co., it is not a dark and evil villain who is plotting the fall of man and his replacement. Instead, Case relationship with artificial intelligence is ambivalent, it suggests a possible fruitful cooperation between man and machine. In contrast, the novel writing quality tempers all these laurels. Neuromancer is very hard to read (read: poorly written): Gibson lacks clarity, goes from cock to donkey and repeatedly loses its drive all three pages. The plot is really not exciting and the author inflicts us indigestible passages worthy psychedelic flights of Kubrick in 2001: A Space Odyssey. In the end something very interesting for any SF reader, but requires a lot of courage ...
