Return to THE RINGWORLD! It's been twenty years since the quixotic and worldsweary Louis Wu discovered the Ringworld. Now he and Speaker-To-Animals are going back, captives of the Hindmost, a deposed puppeteer leader. With Louis' help, the Hindmost intends to regain his status by bringing back such extraordinary treasures from the Ringworld that his fellow puppeteers will have to be impressed. But when they arrive, Louis discovers that the Ringworld is no longer stable ...and will destroy itself within months. To survive he must locate the control center of the legendary engineers who built the planet.
"A remarkably seamless continuation of the first book." (Publishers Weekly)
very good sci-fi. A must read if your a Larry Niven fan.
This follow-up volume to the classic Ringworld explains some of the physical attributes that make the ring environment possible. It also explains the origin of the engineering feat. Unfortunately -- in a flaw continued in the other books in the series -- it veers off the scope of pure hard science fiction into a fantastical story that is less accessible than need be.
Dynamite adventure set in the far future. In the distant past an alien people converted the planets in their solar system to an unbelievably huge ring encircling their sun. This ring was an gigantic plane of habitable space, and it became their new home. After many thousands of years their cultures decayed, and they lost their science. Now the ring is losing its stability, and all the inhabitants risk being killed by technological catastrophies. Into this incredible situation, a group of explorers from the earth of our future are stranded, and they have to figure out what is happening and how to escape. Exciting read - Niven at his best.
Louis and Chmeee are once again trying to escape from the Ringworld. Hindmost is not as interesting as Nessus, and the various natives that Louis picks up are not as interesting as Teela. I'd be a bit more upset at the end than the explorers seem to be, especially if I were the Hindmost. But still very engaging, lots of action, lots of science, cool concepts.
If you haven't read Ringworld - and why haven't you, it's a bona fide classic piece of SF - read it first.
