You Will Know—Singularity! Singularity Sky by Charles Stross
There’s a backstory to my reviewing Singularity Sky. Its 2003 publication date made it chronologically eligible for the 2004 Prometheus Award for Best Novel. But it was Stross’s first book publication, and none of the Libertarian Futurist Society’s members happened to read it until that year’s finalists had already been chosen.
However, there was a campaign to write it in, and in fact it received a substantial number of votes, though not quite enough to win; had it been nominated, it might well have won. Now, much later, it’s eligible for the Hall of Fame Award, which can go to works at least twenty years old — and it’s been nominated for that award. As the chair of the committee that chooses Hall of Fame finalists, I’ve just finished rereading it.
