by Charles Stross – 2005

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 and 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 humanity.

About the title: in Italian, accelerando means “speeding up” and is used as a tempo marking in musical notation. In Stross’s novel, it refers to the accelerating rate at which humanity in general, and/or the novel’s characters, head towards the technological singularity. The term was used earlier in this way by Kim Stanley Robinson in his 1985 novel The Memory of Whiteness and again in his Mars trilogy.
