Time for a new World? Ringworld perhaps?

Ringworld's Children returns Larry Niven devotees to the Ringworld, a flat band 3 million times the surface area of Earth that encircles a distant star, where war and a powerful new weapon threaten the world's stability.

Ringworld's Children is the fourth in Niven's Ringworld saga. Ringworld was published in 1970 and was both a Hugo and Nebula Award winner. The books that precede Ringworld's Children are The Ringworld Engineers (1980) and The Ringworld Throne (1996).
