Iron Sunrise (Ace Science Fiction)

Über

Iron Sunrise is a 2004 hard science fiction novel by author Charles Stross, which follows the events in Singularity Sky. The book was nominated for both the Hugo and Locus Awards in 2005.
Singularity Sky depicts a future where human societies have been involuntarily taken from Earth and widely distributed across the Milky Way galaxy, seemingly at random, in the wake of a technological singularity which has led to the onset of strong AI, in the form of the Eschaton.
The events in both novels take place consecutively some time after the immediate aftermath of the singularity.
