Robert L. Forward_Cheela #1+#2 (Sci-fi) EPUB

In a moving story of sacrifice and triumph, human scientists establish a relationship with intelligent lifeforms--the cheela--living on Dragon's Egg, a neutron star where one Earth hour is equivalent to hundreds of their years. The cheela culturally evolve from savagery to the discovery of science, and for a brief time, men are their diligent teachers . ..



Starquake, the sequel to Dragons Egg, takes place on the surface of a neutron star. The gravity is 67 billion Earth gravities. The native cheela, the size of sesame seeds, live a million times faster than their human friends in orbit. After a starquake, the humans have only one day to save the remains of cheela civilization from extinction.
