The Children of the Sky, a sequel to A Fire Upon the Deep, came out in October 2011. Meanwhile, the Blight is rampaging across the galaxy, so a second expedition is sent in search of the children, on the off-chance that their parents might also have found a counter-measure. The only survivors of the expedition are one family, who flee to a backwater world, where both parents are immediately killed and the children sucked into the power struggles of the medieval-level alien natives. A human expedition to the Transcend releases the Blight, a malignant artificial intelligence which has been dormant for five billion years. The book shares a single character with A Fire Upon the Deep, but is a distant Prequel with a drastically different setting.Ī Fire upon the Deep, which was written first, mostly takes place in the Beyond.

Humanity ignored it for centuries, until possible alien radio signals prompt two nearby cultures to each send a fleet of ships: the Qeng Ho, part of a group of interstellar traders, and the Emergents, an enigmatic civilization that has suddenly raised their technology to high levels. In the Slow Zone, Vinge posits that human technological advance reached an apex with the "Age of Failed Dreams", during which it was discovered that faster than light travel, immortality, strong AI, and a few other things are impossible.Ī Deepness in the Sky takes place in the Slow Zone, next to a very peculiar star. Thus, as you head out of the galaxy, you see the same progression of advancing technologies as you'd expect to see over time if our technology went through a Singularity. In the Unthinking Depths near the core of the galaxy, no intelligence is possible in the Slow Zone, where Earth is, Mundane Dogmatic rules apply the Beyond allows soft SF tropes such as Faster-Than-Light Travel or Antigravity and in the Transcend, everyone is Sufficiently Advanced. In the Zones of Thought verse, the basic gimmick is that The Singularity is turned sideways, becoming a boundary in space instead of time. The Blabber, published in Threats and Other Promises (1988).

It currently consists of three books and one short story: The Zones of Thought is a science-fiction setting created by Vernor Vinge.
