Publisher's Summary

Welcome to Ringworld, an intermediate step between Dyson Spheres and planets. Ninety-three million miles in radius - the equivalent of one Earth orbit or 600 miles long - 1,000 meters thick, and much sturdier than a Dyson sphere.
What other advantages are there to this world? The gravitational force created by a rotation on its axis of 770 miles per second means no need for a roof. Walls 1,000 miles high at each rim will let in the sun and prevent much air from escaping.
Larry Niven's novel, Ringworld, is the winner of the 1970 Hugo Award for Best Novel, the 1970 Nebula Award for Best Novel, and the 1972 Ditmars, an Australian award for Best International Science Fiction.

Genuinely Creative

First the bad news: The book is not world altering, life changing, deep, or otherwise valuable. It is occasionally insightful, but is primarily a romp through a novel and creative universe. As a romp it is first rate.

Niven is excellent at creating novel concepts. He avoids nearly all of the cliches of space-based science fiction. His aliens are first rate, they are truly alien in both form and behavior. His universe has some creative twists, all of which are carefully thought out and explaind to the reader. Niven has a good grasp of the basic concepts of science, technology and engineering. While some of his ideas are fantastic, none of them are laughable.

The plot is well crafted. There are few, if any, loose ends, and only a few minor inconsitencies. All the twists and turns make sense, once you hear them. He avoids the infamous "non-sequitor plot twist."

The voice acting is also quite good. The reader avoids both monotony and over-acting, making it a pleasure, not a chore, to listen to.

All in all this is one of the best quality books I've downloaded.

BREEDING FOR LUCK

YOU CAN LEARN A LOT ABOUT A WORLD, BY LOOKING AT IT'S UNDERSIDE
You must keep in mind that this was published in 1970. It was an excellent book for the time. If you want to say you are a sci-fi lover, than you must do your homework and Niven and this book with The Integral Trees is a most. Even reading it today, you have to be amazed by the size and scope of this artificial world. It was a million miles across. The United States is around 3 thousand miles across. Niven uses a lot of math, but not to the point where the common layman gets lost. Today this is still an interesting read.

YING AND YANG FRIENDSHIP
I thought their was good character development in this book. I especially liked the Puppeteer and the Kzin. These were interesting characters and they added much to the story. I will admit that before it was over I was ready for it to end. Part of that reason maybe because I have read it multiple times. Today's young reader may not be as excited about it as we were in the 70's, but I believe they will still enjoy it.

Vast

The immensities of this structure never fail to amaze me, and Niven's story telling is a gentle introduction into the pure physics of its construction. Fascinating.

Ringworld

Hate the accent of the narrator. The story is my absolute favourite. I really enjoyed listening to this.

I have enjoyed this so much I have planned books for the next 12 months.
