Count Zero

Count Zero (ISBN 0441117732) is a science fiction novel written by William Gibson, originally published in 1986. A prime example of the cyberpunk sub-genre, it is set in the same milieux as Gibson's prior novel Neuromancer, and forms the middle volume of The Sprawl trilogy, which includes Neuromancer, Count Zero, and Mona Lisa Overdrive.

Eight years after the events of Neuromancer, strange things begin to happen in The Matrix, leading to the proliferation of what appear to be voodoo gods.

Two incredibly powerful multinational (and extending to outerspace) corperations are engaged in a battle for control over a powerful new technology (a biochip) using hackers and the Matrix as well as espionage and gun-play.

The name of the book is a word-play of the programming term Count Zero, when in a loop a counter reaches a zero value and therefore exits the loop, it also refers to the nickname of a character of the book Bobby Newmark, Count Zero.
