The Ringworld Engineers Larry Niven

Its been twenty years since the quixotic and worlds-weary Louis Wu discovered the Ringworld. Now he and Speaker-to-Animals are going back, captives of the Hindmost, a deposed puppeteer leader. With Louis help, the Hindmost intends to regain his status by bringing back such extraordinary treasures from the Ringworld that his fellow puppeteers will have to be impressed. But when they arrive, Louis discovers that the Ringworld is no longer stable—and will destroy itself within months. To survive, he must locate the control center of the legendary engineers who built the planet. His quest becomes a wild and gripping venture blended with the mysteries and spectacular technologies that only Larry Niven can conjure.
