Vernor Steffen Vinge is a retired San Diego State University Professor of Mathematics, computer scientist, and science fiction author. He is best known for his Hugo Award-winning novels A Fire Upon The Deep (1992), A Deepness in the Sky (1999) and Rainbows End (2006), his Hugo Award-winning novellas Fast Times at Fairmont High (2002) and The Cookie Monster (2004), as well as for his 1993 essay "The Coming Technological Singularity", in which he argues that exponential growth in technology will reach a point beyond which we cannot even speculate about the consequences.

This is science fiction on the grandest of scales - a cast of thousands set across hundreds of years and in the farthest reaches of Human Space. A prequel to his earlier novel A Fire Upon the Deep, this new novel is epic in scope and a thoroughly riveting read. A Deepness In the Sky is the story of Pham Nuwen, a small cog in the interstellar trading fleet of the Queng Ho. Both they and the Emergents are orbiting Arachna, a dormant planet which will shortly wake up when it’s On/Off star relights after decades of darkness. Both groups hope to exploit the coming age of technology and commerce on Arachna. But while the Queng Ho seek only to trade aggressively, the Emergents plans are far more sinister, amounting to little short of genocide . . .
