Query: A All-Time Classic Must Read For "Sci Fi" Lovers

If you love reading fast-paced, imaginative, inventive stories about special people traveling to amazing worlds, then you'll love Ringworld. You'll meet Nessus the Puppeteer and Speaker-to-Animals (I guess they aren't people, are they?) and Louis Wu and Teela Brown. They get in a craft protected by their trusty General Products hull and take off for the Ringworld. Ringworld's breathtaking size and Larry Niven's breathtaking imagination will keep you reading until the end and leave you wanting more. And of course, there are sequels! This is the real McCoy; accept no substitutes. Also remember: never eat food that has been dropped on the ground, then picked up by a Puppeteer. And *I'm* not going to be the one to tell why no one knows the location of the Puppeteer home world.
