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.

A great listen and worth the "read".

This is one of the first audible books that I had purchased and listened to. I'd heard about this book being in the top 20 lists of many Sci-Fi fans, and decided it was time to give it a listen on Audible. I was not disappointed. The reader is one of the best. It was very easy to discern amongst the many characters because of his changes in his narration. In my minds eye, I could vividly imagine being aboard with Tila and Speaker to Animals, and could see what they looked like, even when someone gets "burned". Great stuff. I would highly recommend this to any Sci-Fi, as well as Audiblefiles must have list.

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.

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.

Not a

I chose this book because I like science fiction, and Ringworld appears to have stood the test of time.

This book didn't exactly inspire me to want to listen to it all in one sitting, but it had enough of consistency and realism that it didn't get dull or boring either.

The strengths of Ringworld are that the framework of the universe in which it takes place is well fleshed-out, the history is developed enough to establish a backdrop for the story, the characters seem internally consistent, and the alien races don't just seem to be "humans with funny ears". Each race has their own motivations, goals, and unique characteristics, and that all combines well to propel the story line forward in a logical and consistent manner.

The primary weakness of Ringworld, in my mind, is that the story isn't exactly compelling reading. Things happen, but there aren't the plot twists, epic struggles, and so on that typically make up a piece of sci-fi....this book flows more like a historical narrative. The ending also left me feeling like there should be more; it just didn't finish well.

That all being said, it's a great book for people who like a more technical science fiction. I am definitely going to be exploring Niven's other Ringworld books. If, however, you're looking for the proverbial "page-turner", I don't think Ringworld is for you.

Still Worth Listening 40 Years Later!

My husband has been telling me about Ringworld for about 10 years now, so when I saw it available on Auidble, I was excited to hear this book, which stuck with him since his teen years. This book is super unique and creative. It doesn't feel dated at all. I also found it to be a very different kind of Sci Fi book, as much about the characters and their personal curiosities as it is about the RingWorld itself.

This is not a rock 'em sock 'em space war sci fi book - it's much more cerebral and about the characters from three different species trying to relate to each other while they learn the secrets of the RingWorld.

My ONLY problem with this book was that it ended rather abruptly! I guess I have to listen to the next in the series. But this book is definitely worth the listen and totally earned it's Hugo!

Big ideas in a grand setting

Orignally posted at FanLit

In 2850 AD, Louis Wu is at his 200th birthday party and thinking about how bored he is. The world has become homogeneous — everyone on Earth uses the same language, everything is available everywhere, and all the cities have lost their unique flavor. Life is dull. That’s why Louis Wu is a perfect candidate for the alien Nessus (a Pierson’s Puppeteer) who wants to take a manned spaceship to explore a strange phenomenon in space.

Nessus also recruits a Kzin named Speaker-to-Animals who is a feline alien from a warlike culture, and the beautiful 20-year-old human woman named Teela Brown that Louis Wu has been sleeping with. She’s so silly that at first it’s not clear what she offers the mission other than good looks, “conical breasts,” a giggle soundtrack, and sexual gratification for Louis Wu (this is something I hate about science fiction written by men in the 1960s), but later we discover that Nessus knows that Teela Brown has lucky genes and he thinks having her along will make the voyage lucky.

When the group stops off at the Puppeteer planet, they learn about their mission. They will investigate the Ringworld. Photos from space show that it looks like a blue ribbon arranged around a star. It’s about the size of the Earth’s orbit around the sun and it’s obviously artificial. The living area inside the ring provides about three times the Earth’s surface area, there’s gravity due to the ring’s centripetal force, and day and light cycles are created by shading the sun with huge panels. (Find the physics of Ringworld here.) The mission seeks to discover who created the Ringworld, why they created it, and whether they’re friendly or threatening.

Ringworld is a high concept novel and I generally love high concept novels. Ringworld has big ideas in a grand setting. Images of Ringworld will stay with me forever. Unfortunately, the characters are dull and the actual action in Ringworld would fill only a few pages. While I wanted to explore and experiment on Ringworld, the characters were usually discussing, bickering, arguing, and philosophizing. Some of this was interesting, such as the discovery that the Puppeteers were covertly performing genetics experiments on other species, the contemplation of what factors might make civilizations rise and fall (cycles of culture and barbarism is also a theme in the last Niven book I read, The Mote in God’s Eye). But much of it was teachy as characters spent too much time explaining evolution, genetics, meteorology, geology, and the physics and mathematics of the shape of orbits, velocities, heat transfer, and tensile strength. Worse, some discussion topics that started out interesting became repetitive and tiresome, especially the philosophical discussions about Teela’s luck which kept coming up and lasting too long.

I love Larry Niven’s big ideas and I know he can write really exciting science fiction even if he can’t write decent female characters. Ringworld is a great idea that gets obliterated by dull characters and too much talking. (Yet it won the Hugo Award, the Nebula Award, and Locus Award.) There are several prequels and sequels to Ringworld in Larry Niven’s RINGWORLD and KNOWN SPACE universes. I listened to Blackstone Audio’s production which was nicely narrated by Tom Parker.

Audible Echos

As far as the story goes, the Ringworld universe is a fascinating place. Unfortunately, Niven doesn't invest as much time into his character interaction as he does into the back story.

On the technical side, there is a definite, annoying ghost echo of the narrator's voice, lagging about a second behind. It's distracting and disappointing to say the least, and something that Audible could fix by running a simple audio filter on it.

The book is a must-read for any science fiction fan; however, its rich descriptions might be better served in their original book form. I often found myself wanting to skip back a few seconds and listen again to certain passages. Still, if you can't find the book, getting the audio book is definitely worth it.

Classic Science Fiction at its Best

Fast paced, extremely unusual characters (as would be expected in any good sci. fi) fun to read even as this strange but fascinating story unfolds. Well produced and read. Has a teensy but-easy-to ignore echo from what tape audio engineers call "print through" (magnetic tape as it lay curled up slightly magnetizing the echo of one loop onto the last wind of the tape.) No big deal.
Easy to see why this one won a Hugo award. This is SERIOUS Science fiction! (not a downer it just has very strange characters) The author is skillful enough to make the extremely strange characters and setting seem normal. If you're not into "extremely weird" - (but again still so very human), you might not enjoy it.

Mediocre story, bad audio quality

Like most hard sci-fi, Larry Niven's Ringworld is not about the characters, but the setting and its technology. In that respect, Ringworld succeeds. Niven has a knack for explaining futuristic technologies in a way that brings them alive to the reader. I only wish that we had learned more of the Ringworld itself.

Ringworld's human characters are boring, and its alien characters are absurd, cartoonish, and uninteresting. Given their dire situation, the characters should be anxious and their relationship complex, but they barely seem to care that their lives are in danger. The characters are so weak, in fact, that I finished the novel a few days ago and I can hardly remember their names.

There are a few moments of tension when we learn of the Puppeteers' history of manipulating other species' evolution for their own benefit, but the situation feels disingenuous, as if their anger is just an inside joke that we know will soon pass. Furthermore, after Teela's disappearance, I was shocked at how quickly everyone wrote her off. But I guess that is excusable because I never once felt attached to any of them either.

The story's plot is simple: the group crash on the Ringworld and need to escape. They run around a bit and explore things before finding a way to get out. Ringworld is a decent read, but I do not understand the hype, nor do I understand why it has won so many awards. It is mediocre in all respects.

While the narrator was quite good, the audio quality is horrible. Aside from the obviously tape-quality audio recording itself, there was a persistent, annoying background echo. Everything the narrator said could be heard duplicated just moments after he said it, as if there was a conversation going on in the background. Sometimes this echo was very obvious and at others it wasn't noticeable. It drove me nuts and I almost stopped listening because of it. The book loses a star for its audio problems.

A most excellent story! Well developed, interesting characters, great storyline and a great concept. I've now noticed there is a whole "Ringworld" series and I hope Audible gets the rest. I would love to revisit the most interesting Ringworld. My only problem was the odd rather truncated ending. I think a few more plot points needed to be completed before he ended it like he did.

Never run out of space again

What can be said about Ringworld that has not been said a thousand times before. The tale of how a rag tag band of people are selected by a mad member of paranoid reclusive alien race to travel to a distant part of the universe to 'see what's there'. This is a reflective book, interested in discussing theoretical concepts about the evolving nature of existence. The reason you have never seen the film of Ringworld is because the book is about ideas not action. Where a lot of things do happen then they are more a framework for discussing why we are who we are and what got us to where we are right now. Many of the concepts are so bizarre by modern standards such as transparent ship hulls and pleasure induced control devices but where The Ringworld is the setting it is the characters and their journey that is the tale to tell here. Some people have called this book boring and the characters unlikeable but this is a slow moving, reflective tale of the human condition as seen by a not always benevolent outsider. This book will make you think, it cannot fail to if you let it into your mind and imagine the possibilities that you can consider from the crew of The Liar.

A classic of science fiction

Over 40 years later, ringworld still remains relevant, intriguing and thought provoking. A great pillar of science fiction which has inspired scores of other stories and films since.

Hardcore Sexist

Would you recommend this book to a friend? Why or why not?

I'd really be enjoying this book if it weren't for... really appalling depictions of women. Not one but two alien races have 'Non-Sentient Females', I'm guessing having his women unprotesting and ready to mate is a major kink for old Larry Niven.
All female characters are described boobs-first, the main character would actually be likeable enough but he treats his girlfriend, who is 180 years younger then him, like she is actually braindead.

What was the most interesting aspect of this story? The least interesting?

The idea of luck being a hereditary trait is pretty fun, as well as them being not able to get hold of anyone 'lucky' because assumedly they themselves are bad news.

What does Tom Parker bring to the story that you wouldn’t experience if you had only read the book?

The voices are good, consistent.

Did Ringworld inspire you to do anything?

I was thinking of making a twitter bot that takes old descriptions of women from sci fi and rewrites them to be about men.
"He was slight, his package conical yet soft'.

A product of the 50s, written in 1970.

The author's attitude to women and sexual politics is extremely hard to take in 2017. Interesting premise and enjoyable story otherwise. The narrator is initially grating, but I got used to him. I don't think I'd seek out more of the narrator's work, but am interested in the rest of the Ringworld series.

Somewhat dated

Well, I made it all the way through but it was a long journey. Whilst competently read the narrator's voice didn't sit well with me. I can imagine what an amazing story this may have been in the 70s but now it is way too long, navel gazing and technical. Bring on The Stainless Steel Rat instead!

Ignore the review about sexism, it's a very good

I was amazed to see Ringworld summed up as being sexist. It was published in 1970 and written in the 60s. Around the time of Benny Hill and Alf Garnet in the UK. So judge a book by enjoyment value, storyline and entertainment value and not 21st century prejudices/ standards.
On to the book. It's a thought provoking classic of science fiction. Well worth reading and enjoying.
