A lot has been written about Ringworld – it is like a cult book, with people analyzing it from all aspects, looking for scientific contradictions, plot inconsistencies….
I just like the book very much. It’s an adventure, with twists and turns, cool character and amazing ideas of technology, devices, tools, Aliens and their behavior and psychology…. Animals and plants, grand planning of stars and constellations – tons of stuff that will keep your brain working, imagining even further into Niven’s wonderful ideas.
I’m avoiding from giving away anything about the plot, to not spoil any of it if you didn’t read it yet. I highly recommend it, and it is an intriguing piece of work.
