Niven, Larry: 

Ringworld is a 1970 science fiction novel, set in Niven's 'Known Space' universe and considered a classic of science fiction literature. Niven later added four sequels and four prequels. (The Fleet of Worlds series, co-written with Edward M. Lerner provides the four prequels as well as Fate of Worlds, the final sequel.) These books tie into numerous other books set in Known Space. Ringworld won the Nebula Award in 1970, as well as both the Hugo Award and Locus Award in 1971.

Very pricey today in true first edition, this is a signed copy of the 1973 Book Club edition. 

'The artefact is a circular ribbon of matter six hundred miles long and ninety million miles in radius. Pierson's puppeteers, the aliens who discovered it, are understandably wary of encountering the builders of such an immense structure and have assembled a team of two humans, a mad puppeteer and a kzin, a huge cat-like alien, to explore it. But a crash landing on the vast edifice forces the crew on a desperate and dangerous trek across the Ringworld. '


Not to be forgotten, Niven collaborated with Jerry Pournelle to produce ‘The Mote in God’s Eye’ - another SF classic.
