What this book is about
Two children survive a catastrophe that releases an ancient and malevolent entity—the Blight—into the galaxy. While they are stranded on a medieval alien world, a ship races to bring them a weapon that may be the only defense. Vernor Vinge's Hugo-winning space opera is built around the concept of 'Zones of Thought'—regions of the galaxy where intelligence and technology operate at different speeds.
