Return to Ringworld... the most astounding engineering achievement ever seen. A realm filled with unfathomable technical marvels, inhabited by several humanoid species, and the setting for some of the most cherished science fiction tales ever penned!
The human Louis Wu, the puppeteer nicknamed the Hindmost, and Acolyte, the Kzin's son known as Chmeee—legendary creatures united once again in the Ringworld's defense. There's a problem with the Protectors. Before they can reach the Ringworld, incoming spaceships are destroyed. There is a vampire mass. If somebody is brave enough to confront the Ghouls and inquire, they will reveal their own objective.
On Ringworld, every race has always had a Protector of their own. It seems that the Ringworld itself need a Protector at this point. Who will occupy the Ringworld Throne, though?
This book serves as the foundation of Niven's engaging and coherent world, which has been the subject of his previous works. "[His] characters and situations are nicely drawn, and his technique is wonderfully polished. It wraps up (maybe) a corner of a very interesting universe."
