William Gibson’s Count Zero (1986) is the second novel in his influential Sprawl trilogy, a foundational series of the cyberpunk subgenre. The narrative follows three separate storylines that gradually converge as they explore The Corporate Commodification of Identity, The Synthesis of Myth and Technology in Cyberspace, and the nuances of Redefining Art and Artistry in the Digital Age. The first novel in the Sprawl series, Neuromancer (1984), won the Hugo, Nebula, and Philip K. Dick awards, firmly establishing Gibson’s reputation in the science fiction genre. Count Zero is set seven years after the events of Neuromancer, in a world transformed by that novel’s climax. Count Zero was nominated for the Nebula, Hugo, and Locus awards.

The novel frequently shifts among the perspectives of three primary characters: Turner, a corporate mercenary; Marly Krushkhova, a disgraced art dealer; and Bobby Newmark, a teenage hacker known as Count Zero.
As the novel opens, Turner is recovering in Singapore after a near-fatal bombing in New Delhi. A Dutch surgeon spends three months reconstructing his body. Upon his release, Turner drifts aimlessly until traumatic memories of a past mission resurface, prompting him to fly to Mexico. In a small beach town, he meets a woman named Allison and gradually begins to recover. One day, as they sit together on a beach, Turner sees an approaching yacht, the Tsushima. He recognizes the yacht and its owner, Conroy, an operative for the Hosaka corporation. Onboard, Conroy reveals that Allison is a Hosaka field psychologist; their entire encounter was a setup to evaluate Turner’s fitness for a new mission: extracting Christopher Mitchell, the lead biochip researcher for rival corporation, Maas Biolabs.
Meanwhile, in Paris, Marly Krushkhova is still smarting over the scandal of having sold a piece of art that was found to be a forgery when she suddenly receives a mysterious job offer from the reclusive billionaire collector, Josef Virek. The interview is conducted via a sensory link, taking place in a past version of Barcelona that has been reconstructed in cyberspace. She meets Virek in a perfect virtual reconstruction of Gaudí’s Güell Park in Barcelona. There, a simulation of Virek explains that he has been confined to a life-support vat for over a decade due to his failing health. He reveals his awareness that her ex-lover, Alain, framed Marly for selling a forged Joseph Cornell box. Now that she has no job and no future, Virek offers her employment. He shows her a mysterious box that resembles the artworks of Joseph Cornell. He has found seven such works, he says, and he wants to hire Marly to find the anonymous artist at any cost. Back in her hotel, Marly receives a holoprojector with images of all seven boxes, realizing Virek’s surveillance network is already tracking her.
In Barrytown, New Jersey, teenage hacker Bobby Newmark, known as Count Zero, attempts his first professional run in the matrix, the digital representation of the world’s data, which is also referred to as “cyberspace.” Using a powerful icebreaker program rented from a dealer named Two-a-Day, he penetrates a heavily defended database. The icebreaker allows hackers to bypass ICE (Intrusion Countermeasures Electronics) programs. The system’s black ice, a particularly deadly ice defense, traps Bobby, inducing cardiac arrest. As he is dying, a mysterious entity, which he perceives as a girl, appears in the matrix. It tells him that the trap is a trick and then frees him from the lethal feedback loop. The shock throws Bobby from his chair, breaking his connection to the matrix, and he passes out.
Conroy takes Turner to a derelict oil rig, the staging point for the extraction of Christoher Mitchell. Turner meets the tech team, which includes a demolitions expert he knows from a previous job. The mission’s console jockeys (professional hackers) are Jaylene Slide and Ramirez; they will use the prototype Maas-Neotek cyberspace decks (sophisticated computers that allow users to interface directly with the matrix). These models have been built with un-replicable biochips. Conroy gives Turner a dossier on Mitchell, which provides an intimate, AI-compiled overview of the scientist’s life. The team moves to the extraction site, an unfinished shopping mall in the Arizona desert near the Maas Biolabs arcology. The plan is for Mitchell to escape the arcology on his own in an ultralight aircraft, after which the team will pick him up and transport him to Mexico.
Marly meets her ex-lover, Alain, who claims to have information about the boxmaker. He shows her a hologram of a box and demands a large reward. Marly is then contacted by Paco, Virek’s human agent. Paco reveals they are monitoring Alain and advises her to pay him, as the money is meaningless to Virek.
Bobby sees a news report about the bombing of his apartment block. He flees but is attacked. Badly wounded, he is found by Jackie, who takes him into the Projects, a massive self-contained community. They then bring him to Two-a-Day, who is with two imposing men, Beauvoir and Lucas. They reveal they are oungans, or Vodou priests, and that Two-a-Day works for them. They had acquired a dangerous, unknown icebreaker and used Bobby as an expendable test subject against a base known to have lethal defenses. They show Bobby a recording of his run, which depicts the strange entity that saved him. They identify it as a Vodou spirit, or loa, called the Virgin of Miracles.
Lucas takes Bobby to the Sprawl to meet the Finn, a notorious information broker who appeared in Neuromancer. At the Finn’s shop, they find the bodies of three Maas assassins who tried to capture him. The Finn reveals he acquired the icebreaker from Wigan “The Wig” Ludgate, a legendary hacker who went mad and now lives in orbit, occasionally sending down software and box-art sculptures to sell.
As Mitchell’s aircraft approaches the extraction site, Turner confronts and kills a team member named Lynch, whom he wrongly believes is Conroy’s secret plant. Immediately after, another operative reveals that she is Conroy’s actual plant. The site is suddenly attacked by an unknown force. Mitchell’s aircraft crashes and Turner runs to the wreckage to find not the scientist, but Mitchell’s teenage daughter, Angela (Angie). Turner escapes with the unconscious Angie just as a massive, non-nuclear explosion obliterates the entire site.
Marly finds Alain murdered in the suburban apartment. Searching the room, she finds his clue: a set of orbital coordinates. Evading Paco and Virek’s agents, she uses cash to hire a freelance tug pilot to take her to the location. En route, Virek contacts her, revealing he knows her destination and believes the boxmaker holds the key to his immortality. The pilot flies Marly to the derelict data cores of the defunct Tessier-Ashpool corporation.
After meeting the Finn, Bobby is left in Jackie’s care. For his protection, she moves him to a nightclub belonging to a famous hacker named Jammer. During a tandem cyberspace run on Jammer’s powerful deck, Jackie and Bobby encounter two loa and, from their interaction, Jackie infers that Lucas has been killed. Soon after, the club is besieged by street gangs. Beauvoir arrives, confirming Lucas was killed by a rocket attack and explaining that the loa are entities that have appeared in the matrix, which they interpret through Vodou. He believes the siege is orchestrated by Maas Biolabs.
Turner lands the jet near his estranged brother Rudy’s farm. Rudy, a tech genius, scans Angie and discovers a mysterious biocircuitry structure grafted throughout her brain. After learning from news reports that Maas has announced Mitchell’s death, Turner and Angie flee in Rudy’s armored hovercraft. They are ambushed by the demolitions expert in a Hosaka helicopter, which Turner rams, killing the expert and the pilot. The shock triggers a trance in Angie, who is possessed by loa that give Turner an address in New York: Hypermart, where Jammer’s club is located. On the way, Turner uses the biosoft dossier again and discovers that Mitchell was not brilliant enough to have invented biochips on his own, concluding his breakthroughs were fed to him by an external source.
Marly enters the Tessier-Ashpool cores and meets their inhabitants: the deranged Wigan Ludgate and a young fugitive named Jones. Jones leads her to a dome where an autonomous construction machine is building the boxes from a swirling cloud of the Tessier-Ashpool clan’s personal effects. Marly communicates with the entity controlling the machine, a fragmented AI. Virek contacts them, announcing he has bought the space station and that Paco is arriving to take possession of the AI.
Turner and Angie arrive at Jammer’s. Conroy calls, revealing he was working for Virek and demanding Turner hand over Angie. In cyberspace, Bobby and Jackie attempt to contact the Yakuza for help, but Jackie is killed by Virek’s defense systems. Bobby is accidentally pulled into Virek’s personal cyberspace construct, where he is possessed by the loa Baron Samedi, who kills Virek within the matrix. Thrown back into cyberspace, Bobby is intercepted by Jaylene Slide, to whom he delivers Turner’s message that Conroy was responsible for her partner’s death. Enraged, Slide launches an attack on Conroy’s office. The siege on Hypermart ends as news reports confirm the deaths of both Conroy and Virek.
In the Tessier-Ashpool cores, Paco announces Virek’s death and terminates Marly’s contract. The AI creates a final box for Marly from her own belongings. At Jammer’s, Beauvoir invites Angie to live in the Projects to learn to control her abilities. Turner tells Angie a fabricated story about her father’s heroic death, gives her the biosoft dossier, and departs. Bobby learns his mother survived the bombing and agrees to move to the Projects with Angie and Beauvoir.
Two years later, Marly is a successful gallery owner in Paris. It is implied that Angie has become a simstim star with Bobby as her bodyguard. Years later, Turner lives with Rudy’s former girlfriend, Sally, and their son, reflecting on his past.
