About this book
In the year 2850, Louis Wu turns 200 and is bored with life. Then a two-headed alien Puppeteer called Nessus offers him a job: join a small expedition to a gigantic artificial ring circling a distant star, a structure of impossible size that no one understands.
Louis, Nessus, a warlike Kzin and a young woman chosen for her extraordinary luck set out to explore it. When their ship is wrecked on the ring's surface, they have to cross a world a million times the size of the Earth to find a way home.
A Hugo and Nebula Award-winning classic of Known Space.
