Ringworld’s Children returns series protagonist Louis Wu to the titular world. Louis and his friend The Hindmost, an alien of the Pierson’s puppeteer race, are prisoners of the Ghoul protector Tunesmith, a Ringworld native, who is deliberately provoking the warships that surround his world. All the star-faring races of Known Space have sent warships to the Ringworld, and they are already at the brink of war. If fighting breaks out, the near-indestructible Ringworld will be destroyed: dissolved by antimatter weapons. The Ringworld series is so complex and ambitious that Ringworld’s Children opens with a glossary and a cast of characters, inclusions that even many Known Space fans will need. Newcomers to Niven’s artificial planet should start with Ringworld .
