The Singularity. It is the era of the posthuman. Artificial intelligences have surpassed the limits of human intellect. Biotechnological beings have rendered people all but extinct. Molecular nanotechnology runs rampant, replicating and reprogramming at will. Contact with extraterrestrial life grows more imminent with each new day.

Struggling to survive and thrive in this accelerated world are three generations of the Macx clan: Manfred, an entrepreneur dealing in intelligence amplification technology whose mind is divided between his physical environment and the Internet; his daughter, Amber, on the run from her domineering mother, seeking her fortune in the outer system as an indentured astronaut; and Sirhan, Amber’s son, who finds his destiny linked to the fate of all of humanity.

For something is systematically dismantling the nine planets of the solar system. Something beyond human comprehension. Something that has no use for biological life in any form...

From Publishers Weekly

Stross (Singularity Sky) explores humanity's inability to cope with molecular nanotechnology run amok in this teeming near-future SF stand-alone. In part one, "Slow Takeoff," "free enterprise broker" Manfred Macx and his soon-to-be-estranged wife/dominatrix, Pamela, lay the foundation for the next decade's transhumans. In "Point of Inflection," Amber, their punky maladjusted teenage daughter, and Sadeq Khurasani, a Muslim judge, engineer and scholar, try to escape the social chaos that antiaging treatments have wreaked on Earth by riding a tin can–sized starship via nanocomputerization to a brown dwarf star called Hyundai. The Wunch, trade-delegation aliens evolved from uploaded lobster mentalities, and Macx's grandson, Sirhan, roister through "Singularity," in which people become cybernetic constructs. Stross's three-generation experiment in stream-of-artificial-consciousness impresses, but his flat characters and inchoate rapid-fire explosions of often muzzily related ideas, theories, opinions and nightmares too often resemble intellectual pyrotechnics—breathtakingly gaudy but too brief, leaving connections lost somewhere in outer/inner/cyber space.

From Booklist

Starred Review During the last five years, Stross has garnered a reputation as one of the most imaginative practitioners of hard sf. Expanded from several stories originally published in Asimov's Science Fiction, Stross' latest novel follows several generations of the Macx family through the rapidly transforming, Internet-enabled global economy of the early twenty-first century to the human and transhuman populated worlds of the outer solar system a half century later. The saga begins with Macx patriarch Manfred, a freelance "venture altruist," giving away patentable high-tech ideas in exchange for endless handouts while looking forward to the day when nanotech-programmed smart matter surpasses humanity in intelligence and productivity. Fifteen years later, his adolescent daughter Amber is an indentured astronaut trolling the orbit of Jupiter, and by 2070, Sirhan is Amber's permanently space-bound offspring, paying witness to the fruits of his grandfather's early innovations as something ominous and nonhuman is systematically dismantling the planets from Pluto to Earth. Stross has his thumb squarely on the pulse of technology's leading edge and exults in extrapolating mere glimmers of ideas out to their mind-bending limits. His brilliant and panoramic vision of uncontrollably accelerating technology vaults him into the front rank of sf trailblazers, alongside Gibson and Stephenson, and promises to become a seminal work in the genre.
