Mona Lisa Overdrive

by William Gibson

Taking place eight years after the events of Count Zero and fifteen years after Neuromancer, the story is formed from several interconnecting plot threads, and also features characters from Gibson's previous works (such as Molly Millions, the razor-fingered mercenary from Neuromancer).

'Thread one': concerns Mona, a teen prostitute who has a more-than-passing resemblance to famed Simstim superstar Angie Mitchell. Mona is hired by shady individuals for a "gig" which later turns out to be part of a plot to abduct Angie.

'Thread two': focuses on a young Japanese girl named Kumiko, daughter of a Yakuza boss sent to London to keep her safe while her father engages in a gang war with other top Yakuza leaders. In London, she is cared for by one of her father's retainers, who is also a powerful member of the London Mob. She meets Molly Millions (having altered her appearance and now calling herself "Sally Shears", in order to conceal her identity from hostile parties who are implied to be pursuing her), who takes the girl under her wing.

'Thread three': follows a reclusive artist named Slick Henry, who lives in a place named Factory in the Dog Solitude; a large, poisoned expanse of deserted factories and dumps, probably in southern New Jersey. Slick Henry is a convicted car thief whose punishment consisted of having his short-term memory erased every five minutes, leading to continuous confusion and dissociation. Following the end of his sentence, he spends his days creating large robotic sculptures and periodically suffers episodes of time loss, returning to consciousness afterward with no memory of what he did during the blackout. He is hired by an acquaintance to look after the comatose "Count" (Bobby Newmark from the second novel, Count Zero, who has hooked himself into a super-capacity cyber-harddrive called an Aleph).

A theoretical "Aleph" would have the RAM capacity to literally contain all of reality, enough that a memory construct of a person would contain the complete personality of the individual and allow it to learn, grow and act independently.

The final plotline follows Angela Mitchell, famous simstim star, and the girl from the second Sprawl novel Count Zero. Angie, thanks to brain manipulations by her father when she was a child, has always had the ability to access cyberspace directly (without a cyberspace deck), but drugs provided by her production company Sense/Net have severely impeded this ability.

The plot culminates when Angie and Bobby "upload" their consciousness into the Aleph, on the verge of visiting an alien artificial intelligence apparently found on a planet orbiting Centauri. Mona takes Angie's place as a simstim star following forced cosmetic surgery to make Mona look identical to Angie.
