Accelerando is a 2005 science fiction novel consisting of a series of interconnected short stories written by British author Charles Stross . As well as normal hardback and paperback editions, it was released as a free e-book under the CC BY-NC-ND license . Accelerando won the Locus Award in 2006,  and was nominated for several other awards in 2005 and 2006, including the Hugo , Campbell , Clarke , and British Science Fiction Association Awards .  
In Italian, accelerando means “speeding up” and is used as a tempo notation in musical notation . In Stross’ novel, it refers to the accelerating rate of the world in general, and / or the novel’s characters, head towards the singularity . The term was earlier used by Kim Stanley Robinson in his 1985 novel The Memory of Whiteness and his 1992-96 March trilogy .
The book is a collection of nine short stories telling the tale of three generations of a family before, during, and after a singularity . It was originally written as a series of novelettes and novellas, all published in the Asimov’s Science Fiction magazine in the period 2001 to 2004. According to Stross, the initial inspiration for the stories was his experience working as a programmer for a high-growth company during the dot-com boom of the 1990s. 
The first three stories follow the character of agalmic “venture altruist ” Manfred Macx, starting in the early 21st century; the second three stories follow his daughter Amber; and the final three focus largely on Amber’s Sirhan sound in the world.
Stross describes the situation at the start of Accelerando as:
In the background of what looks like a Panglossian techno-optimist novel, horrible things are happening. Most of humanity is wiped out, then arbitrarily resurrected in mutilated form by the Vile Offspring. Capitalism eats everything then everything then everything then everything the everything the everything the everything; everything; everything ; we’re a fat, slow-moving, tasty resource – like the dodo. Our narrative perspective, Aineko, is not a talking cat: it’s a vastly superintelligent AI, coolly calculating, that has worked out that they are more easily manipulated if they think they’re dealing with a furry toy. The cat body is a sock puppet wielded by an abusive monster. 
As events progress in Accelerando , the planets of the solar system are dismantled over time to form a Matrioshka brain , a vast solar-powered computational device inhabited by minds inconceivably more advanced and complex than naturally evolved intelligences such as human beings. This proves to be a normal stage in the life-cycle of an inhabited solar system; the galaxies are revealed to be filled with such Matrioshka brains. Intelligent consciousnesses outside of Matrioshka brains can communicate via wormhole networks.
The notion that the universe is dominated by a communications network of superintelligences bears comparison with Olaf Stapledon’s 1937 science fiction novel Star Maker , Stapledon’s advanced civilizations are said to communicate psychically rather than informatically.

Plot summary and breakdown by story
In the following table, chapter name & original magazine date of publication, and a brief synopsis are given. The nine stories are grouped into three parts.
|#||Chapter / Date of original publication||Part 1: Slow Takeoff – Synopsis|
|In early-21st-century Amsterdam , Manfred receives a call from a claimant to a net-based AI working for KGB .ru , seeking his help on how to defect. Eventually, he discovers the callers are actually uploaded brain-scans of the California spiny lobster looking to escape from humanity’s interference. Driven By His commitment to agalmic economics, he marriages to team them up with entrepreneur Bob Franklin, who is looking for an AI crew to His nascent spacefaring project-the building of a self-replicating factory complex from cometarymaterial. A legal precedent is established that will help define the rights of future AIs and uploaded minds. Later, Manfred’s predatory fiancée Pamela forces him to impregnate and marry her in an attempt to control him.|
|Three years later, Manfred is in the throes of an acrimonious divorce, and has a daughter of his marriage to Pamela, frozen as a newly fertilized embryo. He meets Annette again, and begins a relationship with her. Three schemes-a workable state centralized planning apparatus that can interface with external market systems , a way to upload the entirety of the 20th century’s out-of- copyright film and music to the net, and a plan to thwart its fatping wife and her lawyers -come together perfectly. Amber, Manfred’s daughter, has been defrosted and born, and is being brought up by Pamela.|
|In Edinburgh , five years later, Manfred is mugged and his memories (stored in cyberware ) are stolen, forcing him to rediscover who he is and what he’s doing in Edinburgh. Meanwhile, the Lobsters are thriving in colonies located at the L5 point , and one comet in the asteroid belt ; they, along with the Jet Propulsion Laboratory and the ESA , have picked up encrypted signals from outside the solar system . Bob Franklin, now dead, is personality-reconstructed in the Franklin Collective. Manfred, his memories recovered, moves to further expand the rights of non-human intelligences. Aineko begins its own study and decoding of the alien signals.|
|#||Chapter||Part 2: Point of Inflection – Synopsis|
|A decade later, Amber Macx – in his early teens – finally breaks from his dominating motherboard by using a complex plot, thought up by Manfred and Annette, in which she enslaves herself via a Yemeni shell corporation and later enlists aboard to Franklin Collective -owned, youth-crewed spacecraft, mining materials from Amalthea , Jupiter ‘s third moon . Pamela petitions the imam Sadeq to issue an Islamic legal judgment against Amber, which she thwarts by setting up her own empire on a small, privately owned asteroid , thus making herself sovereign. In the meantime, the alien signals have been decoded, and a physical journey to a ” router ” is planned.|
|The alien router, orbiting a 3- light-year- remote brown dwarf star named Hyundai + 4904 / -56, is visited by the spacecraft Field Circus , a Coke -can-sized mass of computronium propelled by a Jupiter-basedlaser and a lightsail . Amber and 62 others have uploadedto become the virtualised crew. They are contacted by a group of aliens called “The Wunch”, who occupy virtual bodies based on Lobster patterns “borrowed” from Manfred’s original transmissions. The Wunch is going to be thieving, third-rate “barbarians” who, after a struggle, are thwarted. Amber and a few others make the decision to go deep into the router’s wormhole network.|
|The router explorers find themselves trapped by yet more malign aliens in a variety of virtual spaces, but are eventually set free by Aineko’s machinations. They discover that they are being hosted in a Matrioshka brain , the builders of whom they have disappeared, leaving an anarchy ruled by sentient, viral corporations and scavengers who attempt to use newcomers as currency. The crew finally escape by Offering transition to a “rogue alien corporation” (a ” pyramid scheme crossed with a 419 scam “) Virtualized have a giant slug , Who opens a powered road out. Thereafter, the crew begins the journey back home.|
|#||Chapter||Part 3: Singularity – Synopsis|
|Back in Earth’s solar system, the crew Find That “home” is now Saturn was floating habitat in the planet’s upper atmosphere, Where They meet Sirhan her of the physical Amber and Sadeq Who Both stayed (and died) at home. The crew uploads their virtual worlds, and they find that they are unable to compete with the new economics 2.0 model practiced by the posthuman intelligences of the inner system. Manfred, Pamela, and Annette are present in various forms. Bailiffs -sent enforcement constructs-arrives to “repossess” Amber and Aineko, but a scheme is hatched to the Slug is introduced to Economics 2.0 , which keeps both constructs very busy.|
|In the most populated Saturnian Floating Cities, Amber, Annette, Gianni and Manfred begin a political campaign to finance a scheme to escape the predictions of the “Vile Offspring” by dayneying an ounce network, with Amber as the leader of the ” Accelerationista “party. She loses the election (to the stay-at-home “conservationist” faction), but once more the Lobsters step in to help, by offering passage to uploads on their large ships.|
|In the centuries following the singularity, the router has, once again, been reached. Learning from it, the refugees have created their own network, enabling them to explore vast distances. Habitats built around Hyundai are home to copies that, including child-clones. Aineko returns to make Manfred an offer that, if he accepts it, will result in Aineko leaving them alone forever.|
