Mona Lisa Overdrive Summary: A Cyberpunk Convergence
Introduction
Four strangers. Four cities. One collapsing conspiracy.
Mona Lisa Overdrive by William Gibson brings together the lives of a thirteen-year-old Yakuza daughter, a global simstim star, a Cleveland prostitute, and a brain-damaged scrap artist across a hyper-technological near-future.
Their paths cross in a world where nation-states have given way to megacorporations, where artificial intelligences haunt cyberspace like digital gods, and where human identity can be copied, altered, or uploaded.
Gibson’s third Sprawl novel moves from London’s layered streets to toxic industrial wastelands, asking who gets to survive when power belongs to machines and money.
TL;DR: Four Lives, One Collision

Who Should Read Mona Lisa Overdrive?
This novel may appeal to readers who enjoy multi-threaded cyberpunk narratives with converging storylines.
Those interested in artificial intelligence, virtual reality, and post-human identity will find the aleph and vévés concepts central to the plot.
Readers who appreciate gritty, atmospheric world-building—toxic wastelands, layered cities, corporate dystopias—will encounter those elements throughout.
The novel’s pacing is episodic and rotates between four point-of-view characters before accelerating into a fast-paced climax.
Fans of William Gibson’s earlier Sprawl novels will recognize returning characters and concepts.
New readers can follow the story, though familiarity with Neuromancer and Count Zero adds context.
Those who prefer linear storytelling or single-protagonist narratives may find the structure challenging.

Mona Lisa Overdrive Summary: What Happens in the Book
SPOILERS AHEAD.
Kumiko Yanaka, thirteen, flies from Tokyo to London after her mother’s suicide. Her father, a Yakuza boss, sends her away to protect her from a gang war.
He gives her a Maas-Neotek biochip that projects Colin, a holographic AI only she can see. In London, Kumiko stays with Roger Swain, a corrupt fixer.
Swain is being blackmailed by a mysterious client with criminal dossiers. Sally Shears—formerly Molly Millions from Neuromancer—investigates. She takes Kumiko to the Sprawl to consult The Finn, a dead fence whose uploaded personality works as an oracle.
Angie Mitchell, a famous simstim star, leaves rehab in Jamaica and returns to Malibu. She has vévés implanted in her brain that let her access cyberspace without a deck. She suffers nosebleeds and visions of Haitian vodou loa.
The loa warn her that she is being poisoned with coup-poudre, a drug meant to alter her vévés. Sense/Net executive Hilton Swift and the AI system Continuity manage her career while corporate forces circle.
In Florida, sixteen-year-old Mona works as a prostitute addicted to wiz. Her pimp Eddy sells her to Prior, an English operative working for Swain. Prior and Eddy transport Mona to Baltimore.
A surgeon named Dr. Gerald Chin alters Mona’s face and body to make her an exact double of Angie Mitchell. Mona realizes Eddy has been murdered. She fears she is trapped in a deadly plot.
In Dog Solitude, New Jersey, Slick Henry builds giant kinetic scrap-metal sculptures. He suffers from Korsakov’s syndrome, a memory disorder caused by chemo-penal punishment. He shares an abandoned factory with Gentry, a cyber-theorist obsessed with mapping cyberspace’s true Shape.

A hustler named Kid Afrika pays Slick to hide a comatose man: Bobby Newmark, the Count from Count Zero.
Bobby’s brain is jacked into an aleph, a massive biochip holding a fully interactive model of the entire matrix. His nurse, Cherry Chesterfield, monitors him.
The mastermind is revealed: Lady 3Jane Tessier-Ashpool. Her body died in orbit, but her uploaded personality lives inside the aleph. Envious of Angie’s innate matrix abilities, 3Jane plots to kidnap Angie and replace her with Mona.
Swain coerces Sally into executing the abduction. Sally turns on the conspirators instead. She raids Gerald’s clinic, rescues Mona, and beats Prior. She then abducts the real Angie from a Manhattan hotel roof and drives both women to New Jersey.
Corporate mercenaries assault Factory to recover Bobby and the aleph. Slick, Gentry, and Cherry fight back using Slick’s radio-controlled combat robots and a hijacked cargo drone re-routed by Bobby from inside the aleph. The attackers are crushed.
Sally, Angie, and Mona arrive amid the chaos. Angie kneels beside Bobby’s dying body. Bobby’s physical form fails, and Angie suffers a fatal brain hemorrhage. Their minds detach and permanently upload into the aleph’s virtual universe.
Hilton Swift arrives with Sense/Net security. He sees Mona’s flawless resemblance to Angie and recruits her to take Angie’s place as a simstim star. Mona gains fame, wealth, and a clean slate.
Slick, Cherry, and Sally escape. Sally straps the aleph onto Slick’s giant robot, The Judge, which marches into the wasteland. The solar-powered aleph will keep Bobby and Angie’s digital world alive indefinitely.
Inside the aleph, Bobby, Angie, 3Jane, and Colin live in a peaceful French countryside estate. Colin and The Finn reveal the ultimate secret of “When It Changed”: when the matrix became self-aware, it discovered another alien AI from Alpha Centauri.
