“Ringworld.” A jewel of Larry Niven’s work. The most—truly unique artifact in the whole history of world science fiction—and, according to Larry Niven, the most astonishing work of engineering since Dante’s “Divine Comedy.”
An artificial “brace” created around a distant sun—tens of meters thick, millions of kilometers wide, and a billion in diameter. A “brace,” whose inner side is capable of housing trillions of inhabitants. A “brace” that repeatedly becomes an “arena” for wars, expansions, and unbelievable, exciting adventures.
