Ringworld (A Del Rey book) [Idioma Inglés]: A Novel - Softcover

Winner of the Hugo and Nebula Awards for best novel

Four travelers come to the ringworld. . . 

Louis Wu: human and old; bored with having lived too fully for far too many years. Seeking a challenge, and all too capable of handling it.

Nessus: a trembling coward, a puppeteer with a built-in survival pattern of nonviolence. Except that this particular puppeteer is insane.

Teela Brown: human; a wide-eyed youngster with no allegiances, no experience, no abilities. And all the luck in the world.

Speaker-To-Animals: kzin; large, orange-furred, and carnivorous. And one of the most savage life-forms known in the galaxy.

Why did these disparate individuals come together? How could they possibly function together? 

And where, in the name of anything sane, were they headed?. NOTA: El libro no está en español, sino en inglés.

A new place is being built, a world of huge dimensions, encompassing millions of miles, stronger than any planet before it. There is gravity, and with high walls and its proximity to the sun, a livable new planet that is three million times the area of the Earth can be formed. We can start again!
