The year is 2380. The Intersolar Commonwealth, a sphere of stars some 400 light-years in diameter, contains more than 600 worlds, interconnected by a web of transport "tunnels" known as wormholes. At the farthest edge of the Commonwealth, astronomer Dudley Bose observes the impossible: Over 1,000 light-years away, a star...vanishes. It does not go supernova. It does not collapse into a black hole. It simply disappears.

Philip K. Dick's post-nuclear-holocaust masterpiece presents a mesmerizing vision of a world transformed, where technology has reverted back to the 19th century, animals have developed speech and language, and humans must deal with both physical mutations and the psychological repercussions of the disaster they have caused.

Cynical, quick-on-the-trigger Takeshi Kovacs, the ex-U.N. envoy turned private eye, has changed careers, and bodies, once more, trading sleuthing for soldiering as a warrior-for-hire and helping a far-flung planet's government put down a bloody revolution.

In the 25th century, humankind has spread throughout the galaxy, monitored by the watchful eye of the U.N. While divisions in race, religion, and class still exist, advances in technology have redefined life itself. Now, assuming one can afford the expensive procedure, a person's consciousness can be stored in a cortical stack at the base of the brain and easily downloaded into a new body (or "sleeve") making death nothing more than a minor blip on a screen.

For nearly a billion years, every known sentient species in the universe has been the result of genetic and cultural guidance - or "uplifting" - by a previously uplifted patron race. Then humans are discovered. Having already uplifted chimps and dolphins, humanity clearly qualifies as an intelligent species, but did they actually evolve their own intelligence, or did some mysterious patron race begin the process, then suddenly abandon Earth?

Microbiologist Michael Cochrane has been murdered. His brother, Paul, wants to find out who did it and why. It's clear that Michael was working with cyanobacteria, the bacteria that crack water molecules and release free oxygen. It's less clear why this would get anybody killed.
