A Fire Upon The Deep (Zones of Thought) 
Faster-than-light travel remains impossible near Earth, deep in the galaxy's Slow Zone--but physical laws relax in the surrounding Beyond. Outside that again is the Transcend, full of unguessable, godlike "Powers." When human meddling wakes an old Power, the Blight, this spreads like a wildfire mind virus that turns whole civilizations into its unthinking tools. And the half-mythical Countermeasure, if it exists, is lost with two human children on primitive Tines World.
Serious complications follow. One paranoid alien alliance blames humanity for the Blight and launches a genocidal strike. Pham Nuwen, the man who knows about Countermeasure, escapes this ruin in the spacecraft Out of Band--heading for more violence and treachery, with 500 warships soon in hot pursuit. On his destination world, the fascinating Tines are intelligent only in combination: named "individuals" are small packs of the doglike aliens. Primitive doesn't mean stupid, and opposed Tine leaders wheedle the young castaways for information about guns and radios. Low-tech war looms, with elaborately nested betrayals and schemes to seize Out of Band if it ever arrives. The tension becomes extreme... while half the Beyond debates the issues on galactic Usenet.
Vinge's climax is suitably mindboggling. This epic combines the flash and dazzle of old-style space opera with modern, polished thoughtfulness. Pham Nuwen also appears in the nifty prequel set 30,000 years earlier, A Deepness in the Sky. Both recommended. --David Langford, Amazon.co.uk
Reviews
Assuredly no grammatical wizard, Vinge nevertheless writes in top-notch style, his sentences neither shining nor worth complaining about, and more than made up for by the wonderful tale he weaves using them. His characters are rich, interesting, flawed and lovable. The alien races are some of the most creative ever produced--strangely human and nevertheless, quite strange. The plot slides like a thunderbolt, gets your heart going with an accelerating pounding.
This is a very complex story, full of captivating characters in richly detailed lands. Jefri and Johanna Olsndot are children stranded on a medieval planet, where the inhabitants are canine creatures that exist in pack forms. The crew (Ravna, Pham, Blueshell, Greenstalk) of a ship named the OOB, races to save them and to retrieve an artifact that just may save the world.
I'll admit, this book is a slow read initially. The first third of it tripped me up with all the high tech space speak. Plus, the author includes many Internet style messages that are pretty much reading email across the universe. These messages are technical soup. Toward the end I found myself just skipping over them.
Once I got past that initial space speak section and into the medieval world (and read far enough to actually understand that the inhabitants were pack creatures) I found myself entranced by this world. I loved seeing the children interact with these creatures. The author did an excellent job with creating a wide variety of personalities, yet blending them all nicely into the story.
Any time the story flipped back to space I found it lagging. Mostly because all the geek speak was over my head. I followed some of it with a struggle between great Powers. And I liked Blueshell and Greenstalk, who are basically plants on wheels and have limited short term memory. That made for some amusing scenes. But overall, the scenes that happened in the skies, weren't as interesting to me as what was going on down below.
Yet, even with that, I loved this story. I can easily see myself skimming through it just to read about this canine pack world again. The culture is that fascinating. Packs of dog like beings who live in a medieval society. They use their mouths to grasp tools just as they do their paws. And they can't get too close to each other or the mind noise that radiates from each pack entity will confuse them. Plus there are two sides at war, so the story is ripe with spies and the race for technological advances to defeat the enemy. All in all, very cool! I'll just skip over all the space talk. :P
