A new generation is growing up on the island paradise of Camelot, ignorant of the Great Grendel Wars fought when their parents and grandparents first arrived on Earth. Setting out to explore the mainland, this group of young rebels feels ready to fight any grendels that get in their way. On Avalon, however, there are monsters that dwarf the ones their parents fought, and as the group will soon learn, monsters also dwell in the human heart. Avalon does not give up her secrets easily, and some of those mysteries are wicked as sin and blacker than the grave.

Avalon was thriving. The cold sleep colonists from Earth had settled on a verdant, livable world. The fast and cunning predators humans named “grendels” were under control, and the mainland outposts well established. Avalon’s new mainland hydroelectric power station was nearly complete, and when on-line would compensate for the nuclear power systems lost in the Grendel Wars. Humans would have power, and with power came the ability to make all the necessities for life. They would survive. They would not survive as a spacefaring people.

Larry Niven and Jerry Pournelle, award-winning authors of such best sellers as Footfall and The Legacy of Heorot, return us to the Mote, and to the universe of Kevin Renner and Horace Bury, of Rod Blaine and Sally Fowler. There, 25 years have passed since humanity quarantined the mysterious aliens known as Moties within the confines of their own solar system.

The gigantic comet had slammed into Earth, forging earthquakes a thousand times too powerful to measure on the Richter scale, tidal waves thousands of feet high. Cities were turned into oceans; oceans turned into steam. It was the beginning of a new Ice Age and the end of civilization. But for the terrified men and women chance had saved, it was also the dawn of a new struggle for survival--a struggle more dangerous and challenging than any they had ever known....

Welcome to Ringworld, an intermediate step between Dyson Spheres and planets. The gravitational force created by a rotation on its axis of 770 miles per second means no need for a roof.
