Over twenty years after returning to Earth from the Ringworld, Louis Wu is kidnapped, along with a warrior kzin named Chmeee, by a Pierson's puppeteer, a brilliant 2-headed alien who calls himself the "Hindmost". The puppeteer hopes to regain status with his fellow citizens by traveling to the Ringworld to bring back treasures. Upon reaching the vast and mysterious Ringworld, Louis and his companions encounter many surprises, including that the Ringworld is unstable. Its billions of inhabitants will die within months if Louis and his companions do not find a way to locate the Control Center of its mysterious builders, the Ringworld engineers, and fix the problem.

about the author:
Born April 30, 1938 in Los Angeles, California. Attended California Institute of Technology; flunked out after discovering a book store jammed with used science fiction magazines. Graduated Washburn University, Kansas, June 1962: BA in Mathematics with a Minor in Psychology, and later received an honorary doctorate in Letters from Washburn. Interests: Science fiction conventions, role playing games, AAAS meetings and other gatherings of people at the cutting edges of science. Comics. Filk singing. Yoga and other approaches to longevity. Moving mankind into space by any means, but particularly by making space endeavors attractive to commercial interests. Several times we've hosted The Citizens Advisory Council for a National Space Policy. I grew up with dogs. I live with a cat, and borrow dogs to hike with. I have passing acquaintance with raccoons and ferrets. Associating with nonhumans has certainly gained me insight into alien intelligences.

In 2015, Larry Niven received the Grand Master Award, given by The Science Fiction & Fantasy Writers of America.
