Starquake
Robert Forward
 This story begins at the exact time that Dragon's Egg (its predecessor) ended, picking up the plot perfectly. As the human scientists in the orbiting ship Dragon Slayer prepare to leave, the Cheela on the star below continue their rapid advance. Starquake centers around two crises. The first is when the human ship is damaged, and the Cheela must repair the ship before tidal forces kill the humans aboard. Then a catastrophic Starquake strikes. Cheela explorers in space survive but have lost the technology to land back on the surface of their world. All Cheela on the surface perish except for four individuals. All succeeding generations of surface Cheela are descended from these four individuals. For a while, the surface Cheela struggle to keep the rudiments of civilization, but eventually a barbarian conqueror arises. The Cheela in space and their human friends watch helplessly as a new dark age ensues. The second half of the story tells the heroic tale of how the space-bound Cheela, with a little help from the humans, eventually are able to land again on the surface, defeat the barbarian tyrant, and start to rebuild Cheela civilization. The first edition cover shown here vividly and accurately depicts the climactic final battle for the surface as described in the novel.
