Ringworld

Larry Niven's Ringworld is one of those classics of science fiction that I've just never gotten around to until now. The mystery of the Ringworld itself is what propelled me through the story so quickly. I'm sufficiently interested enough in the kzin to start my way through the Man/Kzin Wars series soon enough, too. A giant artificial ring, billions of square miles, circles a star far out side of Known Space. A curious party consisting of two humans and two aliens travel to unlock its secrets but end up marooned instead. Interested in the rest of the story and to see the saga of The Fleet of Worlds unfold.
