I totally loved this return to Ringworld, the mysterious artificial world that has the surface area of a million Earths and populated by hundreds of hominid species that have evolved there from human ancestors placed there a half-million years earlier. Since its discovery Ringworld has been the target of multiple alien species now engaged in warfare to gain access to its technology (the “Fringe War”). Destroying the functionality of the Ringworld and thereby killing its inhabitants is one soluti ...more

Ringworld sequels certainly take their time to appear. Tens of years between books and so much information that's just waiting to be forgotten. On the other hand, new discoveries (and re-discoveries) await! Even though Ringworld's Children has been around since 2004, I have only now gotten around to reading it. What's more, a lot of time has passed since I finished The Ringworld Throne. Niven certainly doesn't waste a lot of time chucking a bewildered reader into the thick of things and dragging ...more

(2013 was turning into a stale year for SF. That summer, I really needed the solace of good, hard SF to escape, if just fleetingly, some harsh realities, same reality having given me long days and nights to read and listen. So, without really making a decision to do so but compelled by circumstances, I started a re-read of the Ringworld series. The publication history of the series was such that one book came out every ten years, on average. And so each book read provided a reflection of a de

Much better than Throne, which wasn't too hard to do. In fact you could compare this to the last part of Throne where things heat up with Bram. The difference between the 3rd and 4th novel seem greater than my rating going from a two to a three, but I still can't make myself give this novel a four. It's a short book and wraps up the series in a way that allows me to move on and leave this world behind. I'm glad he eased up on all the Rishathra, because if that had started up again i'm not sure I ...more

If this is Larry niven's new level of writing he should stop.
Chaotic storytelling, no bright new ideas.
Better than the last in the series but it is missing something more....

The 4th and final of the ringworld series. Louis Wu, yet again (still yet?) a slave to the whims of the protectors of ringworld. The ringworld seems to be in danger again, but this time to a fantastic new weapon and the fringe war. Even the awesome intelligence of the protectors are challenged by all the new complications, and the luck of Teela Brown lives on.

When I read books that are part of a series, I always want to know how the story ends. The original Ringworld story was great, and the ser

The resolution of the Ringworld series. For me: too many events, too little explanation, too many coincidences. There's also the question of whether or not to resolve the mysteries of the series. I think some things are richer and more interesting if left to the reader's imagination.

I read the first three books in physical format and was not planning on reading Ringworld's Children as I didn't have a physical copy. I ended up reading it as an ebook so I could get proper closure on the series.

I actually thought the story was pretty good; the plot was more understandable and less convoluted than the previous stories, especially Ringworld Throne. And it does give a decent ending to the series.

I’m surprised there is another after this. The ending was rather conclusive. Story was better than the last one, but did not grip me enough for 4 stars.

I didn’t like the new person who did the voices. (Audiobook)

The Ringworld Children is far superior to the previous Ringworld Throne. There's a return to Louis Wu as the main character. The plot moves steadily along and it is not so concerned with all the inter-species "rituals."

Tunesmith, the Ghoul-turned-Protecter, is performing his duty to protect Ringworld. The Amalgamation of Regional Militia, aka ARM, aka former UN military force, has discovered Ringworld, along with military forces from other worlds, and they are engaging in warfare for Ringworld's

Larry Niven's Ringworld (1970) was originally written as a stand-alone, and won numerous awards. Since then, he has infrequently produced additional sequels, creating a series of which this is #4. I've now read The Ringworld Engineers (1979), The Ringworld Throne (1996), and Ringworld's Children (2004). These later books also integrate significant background started in Larry Niven's Protector (1973). Beyond that Niven and Edward Lerner have written one more sequel, that I have not read - Fate of ...more

I'm changing my mind about this one. I had only remembered it somewhat fondly, but after rereading it, I've got to bump it up because of how satisfying it was. Not only good writing, but it was full of great story, great characters, and the fulfillment of a fear that had followed all of the ringworld books. Well, one of many. I'm referring to poor Louis. I was thrilled and awed and rooting for him the entire way. I wasn't even slightly surprised at the very end, either. It's great to have godlik ...more

Much better than the prior book in the series (The Ringworld Throne), but unfortunately this book wouldn't hardly make sense unless you've made it through the previous one. I'm glad that I continued reading despite that I disliked the last book because overall this book made up for it and more.

My 2004 booklog notes: has moments, but it's very disjointed. I think the most interesting part of the book was the introductory essay, glossary, and cast of characters. Not a good sign. I read RC only a week ago, and it's already fading into the mists of memory. Bottom line: harmless mind-candy. Avoid, if recent Nivens have irritated you.

Fourth in the Ringworld series and theoretically a culmination, but never put it past Niven to find something else to mine. Not the best but it's always fun to visit the Ringworld.

Since, for me, The Ringworld Throne was a bit of a departure of form, a bit of a drawl drawl, and a bit of a disappointment for me compared to the first 2 installations in the Ringworld Tetralogy, this volume turned out to be just what I wanted from the wrap-up finale of the series.

Pretty much everything that made the third novel fall short for me was rectified for this book. For one, a big part of what made The Ringworld Throne a bit of a let down (and let me stress, it was a BIT of a letdown,

I am tempted to give this one 5 stars because of the contrast with The Ringworld Throne, which was a slog to read. This book takes the story to bigger and flashier places, when Ringworld's existence is threatened by a war between different species that have gathered in the system to grab a bite of the Ring. Also, we learn what really happened to Teela Brown, and Niven gets to bust out most of the new big ideas about Ringworld physics he and other people have come up with since the original Ringw ...more

Hah, didn't see this coming. After the pretty boring Ringworld Engineers and the abysmal Ringworld Throne I was pretty afraid Ringworld's Children would be bad. Well, I was surprised.

What is different this time is that the action that takes place is interesting. Or that there actually is action. And that the book feels like science fiction. For some reason the main characters are a lot more interesting than in the two previous books. Also there is almost zero rishatra, thank god.

This is a just above the middle of the road entry into Ringworld series and the Known Space universe. I am invested in this series and the universe now, so I will read or listen to most of them just to find out what happens. Once you get to know Louis Wu, you want to see what becomes of him. There are some interesting developments and the Fringe War introduces some complications to the story which had previously only been Ringworld inhabitants, so I think I enjoyed this more than the previous en ...more

Thirty-some years after Ringworld's appearance, this very good fourth volume was published. I don't think anyone not familiar with the previous volumes would be able to follow this one very well, but it's a real treat for those willing play in what the author calls his "playground for the mind" in the preface. The characters and plot take a back seat to the exploration and speculation of the world itself, and I suppose that the ending isn't really entirely satisfactory, but it's a great installm ...more

It was more interesting than Throne, but it seems Niven ran out of ways for the characters to discover Ringworld history on their own, and had to throw in a character that spent half a chapter filling in details that he probably had been wanting the reader to know for a while (or just only then realized plot holes and did this to quickly fill them in?) As with many of the other books, I often thought "that character wouldn't have done that!"

Book 4 out of a 5 part series. This was tough for me to get through. This felt like a short story with a lot of technical details thrown in to answer what I would assume to be a plethora of fan based questions. I only rate this at three stars because of the paper thin plot line. It was not great enough to keep me from reading the final novel nor bad enough to make me not finish the series.

I liked it... and everything is wrapped up neatly... and explained well.

There are dramatic moments of crashing, smashing, and fighting... there are dramatic moments of families being torn apart... then there is the saving of the Ringworld itself... all in 297 pages! Niven really outdid himself on this one... and cut out all of the fluff and unneeded stuff.

Ringworld is receiving many visitors from outside who wish to explore or invade. They also fight each other or are destroyed by a Protector (of which there are several with different agendas). Louis Wu is trying to figure out what to do amidst the fighting and sex.

Much of the backstory about Pak and Protectors is explained.

Somewhat better than the 3rd book, but still suffering from the 'too many threads happening at once, and it all resolves super-duper quickly in not-that-satisfying-ways' that the previous 2 books of the series suffered from. Still a fun bit of reading in the Known Space universe.

Also, at what point did Niven decide that ships vanishing when near stars/planets wasn't due to their singularity, but do to some weird dark matter predators? What does that do to the continuity of the unive

His work is primarily hard science fiction, using big science concepts and theoretical physics.
